Technical Specifications

Why Choose the Additel ADT 875-1210?

The Additel ADT 875-1210 Reference Calibration Furnace was designed for users with particularly demanding requirements for their high temperature reference source. Within the high temperature product range, Additel positions the ADT 878 as the reference model, while the ADT 875 provides the standard solution.

A key advantage is the higher specified display accuracy. Depending on the temperature point, the ADT 875-1210 provides specified display accuracy from ±1.0 °C to ±1.5 °C. The standard ADT 875-1210, by comparison, provides specified display accuracy from approximately ±1.2 °C to ±2.0 °C, depending on temperature.

Temperature distribution is equally important for professional calibration applications. The patented multi-zone temperature control supports a stable and uniform heat source, creating suitable conditions for reproducible comparison calibrations.

The 0.01 °C temperature resolution enables precise temperature setting and monitoring. The large color touchscreen also simplifies operation during daily laboratory work.

USB, LAN, WiFi and Bluetooth connectivity allow the reference calibration furnace to be integrated into modern laboratory environments. With the optional Process Calibrator functionality, thermocouples and transmitters can also be measured directly and additional calibration tasks can be documented.

The Additel ADT 875-1210 therefore combines a powerful high temperature source, high metrological performance and flexible expansion capabilities.

Additel ADT 875-1210 or ADT 875-1210?

Additel provides two performance levels for high temperature calibration applications.

The Additel ADT 875-1210 is designed as a standard calibration furnace and is suitable for numerous professional and industrial calibration applications. The Additel ADT 875-1210, in contrast, is the reference version for applications with higher metrological requirements.

Both models cover a temperature range from 100 °C to 1,210 °C and use a flexible concept based on multi-zone temperature control and interchangeable metal inserts.

One of the main differences is the higher specified display accuracy of the ADT 875-1210. At 1,210 °C, Additel specifies a display accuracy of ±1.5 °C for the reference model. For the standard ADT 875-1210, the specified display accuracy at the same temperature is ±2.0 °C.

For professional industrial calibration tasks requiring a powerful high temperature source, the Additel ADT 875-1210 provides an alternative within the standard product line. The Additel ADT 875-1210 is designed for reference applications and calibration laboratories with more demanding metrological requirements.

Additional Models in the Additel ADT 878 Series

In addition to the Additel ADT 878-1210, the ADT 878 product family includes several reference dry well calibrators for lower temperature ranges.

For applications below ambient temperature, the Additel ADT 878-160 covers a temperature range from −40 °C to 160 °C. It also supports the optional ADT 878-TPW-KIT for automated realization and maintenance of the triple point of water.

For medium temperature applications, the Additel ADT 878-425 covers temperatures from 33 °C to 425 °C and provides excellent stability and temperature uniformity for demanding comparison calibrations.

For higher temperature PRT calibration, the Additel ADT 878-700 extends the operating range up to 700 °C and additionally provides an integrated automatic annealing function for high quality PRT sensors.

The Additel ADT 875-1210 completes the series for high temperature thermocouple calibration up to 1,210 °C.

Users can therefore select between the ADT 878-160, ADT 878-425, ADT 878-700 and ADT 875-1210 according to the required temperature range, sensor type and metrological requirements.

Typical Calibration Applications with the Additel ADT 875-1210

The Additel ADT 875-1210 is particularly suitable for high quality comparison calibration of thermocouples and other temperature probes. Its temperature range from 100 °C to 1,210 °C covers numerous high temperature applications in calibration laboratories, industry and research.

In a typical comparison calibration, the reference probe and device under test are positioned in an appropriate insert. Multi-zone temperature control provides a highly uniform temperature zone. Once stability has been reached, the measurement values from the reference and device under test can be compared and documented.

The optional Process Calibrator version further expands the application range. Thermocouples can be measured directly, while temperature switches and transmitters can be integrated into corresponding test procedures. Optional HART communication additionally supports compatible intelligent temperature transmitters.

For applications with less demanding reference accuracy requirements, the Additel ADT 875-1210 provides the standard version. For other temperature ranges, additional models from the ADT 875 and ADT 878 product families are available.

Additional solutions for professional temperature calibration are available from europascal in the Dry Well Calibrators category.
