| Temperature | Calibrated Accuracy |
|---|---|
| −40 °C | ±0.025 °C |
| 0.01 °C | ±0.015 °C |
| +160 °C | ±0.025 °C |
These values are specified with a coverage factor of k = 2 and include calibration and the manufacturer’s defined drift contribution.
The accuracy values demonstrate the suitability of the thermometer for demanding comparison calibrations.
For metrological applications, the uncertainty of the complete measurement system must also include the resistance readout, temperature source and relevant application-specific influences.
Excellent Short-Term Stability
The Additel AccuMac AM 1710 provides excellent short-term stability.
The manufacturer specifies:
< 0.007 °C
This characteristic describes the ability of the thermometer to maintain a stable indication over a short period under defined conditions.
Good short-term stability is particularly important when performing comparison measurements.
It helps reduce measurement variations during calibration procedures.
The stable sensing element makes the AM 1710 suitable for applications requiring repeatable temperature measurements.
Low Long-Term Drift
The Additel AccuMac AM 1710 is designed for excellent long-term stability.
The manufacturer specifies a long-term drift of:
< 0.01 °C
This value refers to measurements at the triple point of water after 100 hours of exposure to 160 °C.
The actual drift of a thermometer depends on its handling, operating conditions and maintenance.
Regular recalibration is recommended to monitor changes in the thermometer characteristics.
For demanding applications, intermediate checks at a suitable reference temperature can help identify unexpected changes.
Excellent Resistance to Thermal Shock
The Additel AccuMac AM 1710 is designed to withstand repeated temperature changes.
The manufacturer specifies a thermal shock effect of:
< 0.005 °C
This value applies after ten thermal cycles between the minimum and maximum operating temperatures.
The sensing element is protected by a specially designed support structure.
This construction helps reduce mechanical stress on the platinum sensing wire.
It also contributes to the thermometer’s excellent repeatability.
Low Temperature Hysteresis
The Additel AccuMac AM 1710 provides low temperature hysteresis.
The manufacturer specifies:
≤ 0.005 °C
Temperature hysteresis describes the difference in thermometer indication that may occur when the same temperature is approached from different directions.
Low hysteresis is particularly important for calibration procedures involving both heating and cooling sequences.
The special sensing element construction helps minimize these effects.
Platinum Resistance Sensor
The Additel AccuMac AM 1710 uses a precision platinum resistance sensing element.
The nominal resistance is:
100 Ω at 0.01 °C
The temperature coefficient is:
0.003925 Ω/Ω/°C
This coefficient differs from the commonly used industrial Pt100 coefficient of 0.00385 Ω/Ω/°C.
Therefore, the AM 1710 should not automatically be configured as a standard IEC 60751 Pt100 sensor.
For accurate temperature measurements, the resistance readout must use the correct thermometer characteristics and the individual calibration coefficients.
The thermometer is designed to meet the relevant ITS-90 criteria for reference thermometers.
Four-Wire Resistance Measurement
The Additel AccuMac AM 1710 features a four-wire connection.
Four-wire resistance measurement minimizes the influence of lead resistance.
This is particularly important when measuring small resistance changes with high accuracy.
The thermometer is equipped with four insulated copper leads.
A suitable precision thermometer readout or resistance measurement instrument is required.
The reference thermometer itself does not contain an integrated temperature display.
Fast Response Time
The Additel AccuMac AM 1710 provides a response time of approximately:
9 seconds
This value refers to the time required to reach 63% of a temperature step change in moving water under the manufacturer’s specified conditions.
The actual response time depends on the measurement medium, flow conditions and immersion depth.
Fast response improves efficiency when performing temperature comparison measurements.
Stainless Steel Construction
The Additel AccuMac AM 1710 features a stainless steel probe sheath.
The sheath protects the platinum sensing element against mechanical damage.
The manufacturer specifies a probe diameter of:
6.35 mm
The stainless steel construction provides durability for regular laboratory use.
The thermometer should nevertheless be handled carefully to avoid mechanical stress and damage to the sensing element.
Straight and Angled Versions
The Additel AccuMac AM 1710 is available in two mechanical configurations.
AM1710-12
The straight version features a probe length of:
305 mm
The probe diameter is:
6.35 mm
This configuration is suitable for conventional calibration baths and dry block calibrators.
AM1710-BEND
The angled version features a 90-degree bend.
The manufacturer specifies approximately:
178 mm from the probe tip to the bend
and:
101.6 mm from the bend to the handle
The angled configuration is useful when installation space is limited.
It can also simplify measurements in calibration equipment where a straight probe would be difficult to position.
Sensor Element Dimensions
The platinum sensing element has a length of approximately:
32 mm
The sensing element is positioned approximately:
3 mm from the probe tip
The sensing element position is important when determining the required immersion depth.
For accurate calibration, the entire sensing element must be exposed to a sufficiently uniform temperature.
Additional immersion depth may be required to reduce heat conduction effects along the probe stem.
High Insulation Resistance
The Additel AccuMac AM 1710 provides high electrical insulation resistance.
The manufacturer specifies:
> 1000 MΩ at room temperature
High insulation resistance helps minimize measurement errors caused by leakage currents.
This characteristic is particularly important for precision resistance thermometry.
The insulation resistance should be monitored if the thermometer is exposed to demanding environmental conditions.
Compatibility with Precision Thermometer Readouts
The Additel AccuMac AM 1710 can be used with suitable precision thermometer readouts.
Examples include compatible Additel reference thermometer instruments.
The Additel 282 dual-channel reference thermometer readout and the Additel 286 multifunction reference thermometer readout are potential components of a precision temperature measurement system.
The selected readout must support the required four-wire resistance measurement and the thermometer’s calibration characteristics.
Depending on the connector configuration, an appropriate adapter may be required.
Available Connection Options
The Additel AccuMac AM 1710 is available with different connection options.
These include:
ADT smart connection
and:
SP spade connection
The ADT smart connector is designed for compatible Additel temperature measurement equipment.
Spade connections allow use with suitable four-wire resistance measurement instruments.
The appropriate connection type should be selected according to the intended thermometer readout.
ISO/IEC 17025 Accredited Calibration Included
The Additel AccuMac AM 1710 is supplied with an ISO/IEC 17025 accredited calibration.
This provides documented metrological traceability for the reference thermometer.
The calibration certificate contains information relevant to the individual thermometer.
