generation from:<\/p>\n<p><strong>100 \u00b0C<\/strong><\/p>\n<p>to:<\/p>\n<p><strong>1210 \u00b0C<\/strong>.<\/p>\n<p>This broad range makes the furnace suitable for thermocouples used in industrial processes where temperatures extend beyond the capabilities of conventional portable dry block calibrators.<\/p>\n<p>Typical applications include:<\/p>\n<ul>\n<li>Type K thermocouple calibration<\/li>\n<li>Type N thermocouple calibration<\/li>\n<li>Type S thermocouple calibration<\/li>\n<li>Type R thermocouple calibration<\/li>\n<li>Type B thermocouple

applications<\/li>\n<li>Laboratory temperature calibration<\/li>\n<li>Industrial temperature metrology<\/li>\n<\/ul>\n<p>The 1210 \u00b0C upper temperature limit makes the ADT 875-1210 an attractive solution for laboratories that need to extend their calibration capabilities into the high-temperature range.<\/p>\n<h2>Display Accuracy up to 1210 \u00b0C<\/h2>\n<p>The <strong>Additel ADT 875-1210<\/strong> provides specified display accuracy across its complete temperature range.<\/p>\n<p>The manufacturer specifies:<\/p>\n<p><strong>\u00b11.2 \u00b0C at 100 \u00b0C<\/strong><\/p>\n<p><strong>\u00b11.2 \u00b0C at 300 \u00b0C<\/strong><\/p>\n<p><strong>\u00b11.2 \u00b0C at 600 \u00b0C<\/strong><\/p>\n<p><strong>\u00b11.6 \u00b0C at 900 \u00b0C<\/strong><\/p>\n<p><strong>\u00b12.0 \u00b0C at 1210 \u00b0C<\/strong>.<\/p>\n<p>These specifications refer to the internal temperature indication of the calibration furnace.<\/p>\n<p>For demanding comparison calibrations, an external calibrated reference thermocouple can additionally be used to determine the reference temperature independently of the internal furnace indication.<\/p>\n<h2>Temperature Stability of \u00b10.1 \u00b0C<\/h2>\n<p>Temperature stability is one of the most important characteristics of a thermocouple calibration furnace.<\/p>\n<p>The <strong>Additel ADT 875-1210<\/strong> provides specified stability of:<\/p>\n<p><strong>\u00b10.1 \u00b0C<\/strong>.<\/p>\n<p>Stable temperature conditions allow the reference thermocouple and devices under test to be compared under consistent thermal conditions.<\/p>\n<p>This becomes increasingly important at high temperatures, where furnace regulation, sensor loading and thermal gradients can significantly influence the calibration result.<\/p>\n<h2>Advanced Adaptive Control<\/h2>\n<p>The <strong>Additel ADT 875-1210<\/strong> uses Additel&#8217;s Advanced Adaptive Control technology.<\/p>\n<p>This innovative control concept combines:<\/p>\n<p><strong>advanced wind-tunnel control technology<\/strong><\/p>\n<p>with:<\/p>\n<p><strong>three-zone temperature control<\/strong>.<\/p>\n<p>Instead of controlling the furnace as a single thermal zone, the system manages the temperature distribution to achieve improved stability and uniformity within the usable calibration region.<\/p>\n<p>The technology is designed to improve:<\/p>\n<ul>\n<li>Temperature stability<\/li>\n<li>Axial temperature uniformity<\/li>\n<li>Radial temperature uniformity<\/li>\n<li>Response to sensor loading<\/li>\n<li>Overall calibration performance<\/li>\n<\/ul>\n<p>This is particularly important when several thermocouples are inserted into the furnace simultaneously.<\/p>\n<h2>Axial Temperature Uniformity<\/h2>\n<p>The temperature along the insertion depth of a calibration furnace is not perfectly constant.<\/p>\n<p>For the <strong>Additel ADT 875-1210<\/strong>, Additel specifies axial uniformity over a 20 mm zone of:<\/p>\n<p><strong>\u00b10.6 \u00b0C at 100 \u00b0C<\/strong><\/p>\n<p><strong>\u00b11.2 \u00b0C at 300 \u00b0C<\/strong><\/p>\n<p><strong>\u00b11.5 \u00b0C at 600 \u00b0C<\/strong><\/p>\n<p><strong>\u00b11.5 \u00b0C at 900 \u00b0C<\/strong><\/p>\n<p><strong>\u00b11.5 \u00b0C at 1210 \u00b0C<\/strong>.<\/p>\n<p>These values are particularly relevant when estimating the measurement uncertainty of a thermocouple comparison calibration.<\/p>\n<p>Correct and repeatable immersion of both the reference thermocouple and the thermocouples under test is therefore essential.<\/p>\n<h2>Radial Temperature Uniformity<\/h2>\n<p>The <strong>Additel ADT 875-1210<\/strong> also provides specified radial temperature uniformity.<\/p>\n<p>Additel specifies:<\/p>\n<p><strong>\u00b10.2 \u00b0C at 100 \u00b0C<\/strong><\/p>\n<p><strong>\u00b10.3 \u00b0C at 300 \u00b0C<\/strong><\/p>\n<p><strong>\u00b10.4 \u00b0C at 600 \u00b0C<\/strong><\/p>\n<p><strong>\u00b10.8 \u00b0C at 900 \u00b0C<\/strong><\/p>\n<p><strong>\u00b11.0 \u00b0C at 1210 \u00b0C<\/strong>.<\/p>\n<p>Radial uniformity describes temperature differences between different positions within the insert.<\/p>\n<p>This is particularly important when several thermocouples are calibrated simultaneously.<\/p>\n<p>The reference sensor and devices under test should be positioned according to the calibration procedure so that radial temperature differences are appropriately considered.<\/p>\n<h2>Low Loading Effect<\/h2>\n<p>Inserting several thermocouples into a furnace changes the thermal conditions.<\/p>\n<p>This is known as the loading effect.<\/p>\n<p>For the Additel ADT 875-1210, the specified loading effect is:<\/p>\n<p><strong>\u00b10.5 \u00b0C<\/strong>.<\/p>\n<p>The Advanced Adaptive Control and multi-zone temperature control are designed to minimize this influence.<\/p>\n<p>For professional calibration, loading should nevertheless be considered as part of the calibration procedure and measurement uncertainty analysis.<\/p>\n<h2>Interchangeable Metallic Inserts<\/h2>\n<p>The <strong>Additel ADT 875-1210<\/strong> uses interchangeable metallic inserts.<\/p>\n<p>Different insert configurations are available to accommodate thermocouples with different diameters.<\/p>\n<p>This allows one furnace to be adapted to different sensor populations.<\/p>\n<p>Appropriate bore diameter is important for good thermal contact between the thermocouple sheath and the insert while still allowing safe insertion and removal.<\/p>\n<p>The interchangeable insert concept therefore provides both flexibility and practical advantages for calibration laboratories handling different sensor designs.<\/p>\n<h2>Designed for Thermocouple Calibration<\/h2>\n<p>The Additel ADT 875-1210 is specifically designed for high-temperature thermocouple calibration.<\/p>\n<p>Thermocouples are commonly used in applications such as:<\/p>\n<ul>\n<li>Industrial furnaces<\/li>\n<li>Heat-treatment equipment<\/li>\n<li>Metal processing<\/li>\n<li>Glass manufacturing<\/li>\n<li>Ceramics<\/li>\n<li>Power generation<\/li>\n<li>Process plants<\/li>\n<li>Research laboratories<\/li>\n<li>High-temperature test systems<\/li>\n<\/ul>\n<p>The ADT 875-1210 provides a controlled heat source for comparing these sensors with an appropriate calibrated reference thermocouple.<\/p>\n<h2>Comparison Calibration with a Reference Thermocouple<\/h2>\n<p>A typical professional calibration setup consists of:<\/p>\n<p><strong>Additel ADT 875-1210 + Reference Thermocouple + Thermocouple Under Test<\/strong><\/p>\n<p>The reference thermocouple and device under test are inserted into the furnace at comparable immersion depths.<\/p>\n<p>The furnace is set to the required calibration temperature.<\/p>\n<p>After sufficient stabilization, the reference temperature and the thermoelectric voltage or indicated temperature of the device under test are recorded.<\/p>\n<p>This procedure is repeated at the required calibration temperatures.<\/p>\n<p>For professional calibration work, factors such as sensor immersion, furnace uniformity, stability, reference sensor uncertainty, thermocouple inhomogeneity and electrical measurement uncertainty must be considered.<\/p>\n<h2>Optional ADT 875PC-1210 Process Calibrator<\/h2>\n<p>The <strong>Additel ADT 875-1210<\/strong> can be ordered with integrated process calibration electronics as the:<\/p>\n<p><strong>ADT 875PC-1210<\/strong>.<\/p>\n<p>This option significantly expands the capabilities of the calibration furnace.<\/p>\n<p>The process calibrator provides multiple measurement channels for thermocouples and electrical process signals.<\/p>\n<p>Supported thermocouple types include:<\/p>\n<ul>\n<li>Type S<\/li>\n<li>Type R<\/li>\n<li>Type K<\/li>\n<li>Type B<\/li>\n<li>Type N<\/li>\n<li>Type E<\/li>\n<li>Type J<\/li>\n<li>Type T<\/li>\n<li>Type L<\/li>\n<li>Type U<\/li>\n<\/ul>\n<p>This allows the furnace to generate the required temperature while simultaneously measuring the reference thermocouple and devices under test.<\/p>\n<h2>Four Device-Under-Test Channels<\/h2>\n<p>The process calibrator option provides:<\/p>\n<p><strong>four device-under-test thermocouple channels<\/strong>.<\/p>\n<p>This enables several thermocouples to be calibrated during the same temperature cycle.<\/p>\n<p>For laboratories handling larger batches of thermocouples, this can significantly improve productivity.<\/p>\n<p>Instead of heating and cooling the furnace separately for every individual sensor, multiple devices can be compared with the reference during the same calibration sequence.<\/p>\n<h2>Dedicated Reference Thermocouple Channel<\/h2>\n<p>The PC option also provides a dedicated reference thermocouple channel.<\/p>\n<p>This allows an external reference-grade thermocouple to be connected directly to the calibration furnace.<\/p>\n<p>The reference thermocouple can then be used to determine the actual calibration temperature more accurately than relying solely on the furnace&#8217;s internal display.<\/p>\n<p>The external reference can also be used for control functions, helping to reduce uncertainty contributions associated with the internal control sensor.<\/p>\n<h2>Electrical Measurement Functions<\/h2>\n<p>The <strong>ADT 875PC-1210<\/strong> provides additional electrical measurement capabilities.<\/p>\n<p>These include:<\/p>\n<p><strong>Current measurement from -30 mA to +30 mA<\/strong><\/p>\n<p>and voltage measurement ranges of:<\/p>\n<p><strong>-12 V to +12 V<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>-30 V to +30 V<\/strong>.<\/p>\n<p>The process calibrator also provides:<\/p>\n<p><strong>24 V DC loop power<\/strong><\/p>\n<p>with a maximum output current of 60 mA.<\/p>\n<p>These capabilities make the system suitable not only for thermocouples but also for temperature transmitters and process instrumentation.<\/p>\n<h2>HART Communication<\/h2>\n<p>The process calibrator option supports HART communication.<\/p>\n<p>This allows compatible smart temperature transmitters to be configured and evaluated directly from the calibration system.<\/p>\n<p>For process calibration applications, the combination of:<\/p>\n<ul>\n<li>Temperature generation<\/li>\n<li>Thermocouple measurement<\/li>\n<li>Current measurement<\/li>\n<li>Voltage measurement<\/li>\n<li>Loop power<\/li>\n<li>HART communication<\/li>\n<\/ul>\n<p>can reduce the number of separate instruments required at the calibration workstation.<\/p>\n<h2>Task Documentation<\/h2>\n<p>The <strong>ADT 875PC-1210<\/strong> provides documenting functionality for structured calibration workflows.<\/p>\n<p>Up to:<\/p>\n<p><strong>1,000 tasks<\/strong><\/p>\n<p>can be stored.<\/p>\n<p>Each task can contain up to:<\/p>\n<p><strong>10 results<\/strong><\/p>\n<p>with as-found and as-left information.<\/p>\n<p>The system also supports functions such as screen capture, automatic stepping and ramp recording.<\/p>\n<p>These features help improve efficiency and documentation during repetitive calibration work.<\/p>\n<h2>Modern Communication and Touchscreen Operation<\/h2>\n<p>The <strong>Additel ADT 875-1210<\/strong> uses a modern color touchscreen interface.<\/p>\n<p>Communication capabilities include:<\/p>\n<ul>\n<li>USB<\/li>\n<li>Wi-Fi<\/li>\n<li>Bluetooth<\/li>\n<\/ul>\n<p>These interfaces support integration into modern calibration environments and simplify remote operation, firmware management and data handling.<\/p>\n<h2>ISO 17025 Accredited Calibration Included<\/h2>\n<p>Each <strong>Additel ADT 875-1210<\/strong> is tested and calibrated in Additel&#8217;s accredited laboratory.<\/p>\n<p>The furnace is supplied with an:<\/p>\n<p><strong>ISO 17025-accredited calibration certificate with data<\/strong>.<\/p>\n<p>According to Additel, the supplied calibration data includes information relating to:<\/p>\n<ul>\n<li>Accuracy<\/li>\n<li>Stability<\/li>\n<li>Uniformity<\/li>\n<\/ul>\n<p>This provides valuable information about the individual furnace and supports professional metrological
