The Additel ADT 110 Short Probe Calibration Kit is a specialized temperature calibration accessory designed for accurate and reliable calibration of short temperature probes, sensors and transmitters. Developed for use with compatible Additel dry well calibrators, the Additel ADT 110 provides a practical solution for one of the most challenging tasks in temperature metrology: calibrating sensors with limited immersion depth.
Conventional dry well calibration can become difficult when temperature sensors have short insertion lengths. Insufficient immersion can introduce significant measurement errors caused by heat conduction, temperature gradients and differences between the reference sensor and the device under test.
The Additel ADT 110 addresses these challenges through specially designed calibration inserts and a compact reference temperature probe. This combination helps improve thermal coupling and allows the sensing elements of the reference probe and device under test to be positioned at similar depths.
The kit is specifically designed for use with the Additel ADT 875-155 and Additel ADT 878-160 temperature calibrators.
At europascal, customers benefit from professional expertise in temperature calibration, precision measurement technology and reliable calibration solutions.

High Accuracy Temperature Calibration
The Additel ADT 110 Short Probe Calibration Kit is designed to improve temperature calibration results when working with short immersion probes.
One of the main challenges in dry well calibration is the influence of heat conduction along the sensor shaft.
When a temperature probe cannot be inserted sufficiently deeply into the calibration block, heat can flow between the sensing element and the surrounding environment.
This can cause the sensor temperature to differ from the actual reference temperature.
The Additel ADT 110 reduces these effects through specially designed inserts and a compact reference probe.
By positioning the sensing elements of the reference and test probes at similar depths, temperature differences caused by axial gradients can be reduced.
This arrangement helps improve measurement reliability and supports calibration procedures with lower uncertainty.
The achievable calibration uncertainty depends on the sensor design, operating temperature, reference thermometer, dry well performance and measurement conditions.
Specialized Calibration Inserts
The calibration inserts are essential components of the Additel ADT 110 system.
Each kit includes three standard inserts and one blank insert.
The standard inserts are designed for commonly used temperature probe diameters.
The blank insert can be modified by the user to accommodate special sensor dimensions.
This provides additional flexibility when calibrating temperature probes with unusual mechanical designs.
Metric Calibration Inserts
The metric kit includes inserts with the following nominal diameters:
- 3 mm
- 4 mm
- 6 mm
These sizes are commonly used for industrial temperature sensors and compact reference probes.
Imperial Calibration Inserts
The imperial kit includes inserts with the following nominal diameters:
- 1/8 inch
- 3/16 inch
- 1/4 inch
This configuration is suitable for temperature probes manufactured according to imperial dimensional standards.
Custom Calibration Insert
The additional blank insert can be machined to accommodate special probe dimensions.
This is particularly useful for calibration laboratories that regularly work with different sensor designs.
Correct machining and suitable thermal contact are important for achieving reliable calibration results.
AM1611 Secondary Reference Temperature Probe
An important component of the Additel ADT 110 is the included AM1611 secondary reference temperature probe.
The AM1611 is a compact platinum resistance thermometer designed for precise temperature measurements.
Its small sensing element allows it to be positioned close to the sensing element of the device under test.
This arrangement helps reduce temperature differences between the reference sensor and the test probe.
The AM1611 has a nominal resistance of 100 Ω at 0 °C and a temperature coefficient of 0.00385 Ω/Ω/°C.
Its specified temperature range extends from -40 °C to 160 °C.
The reference probe provides an accuracy of ±0.05 °C at 0 °C.
It also features excellent short term stability and low hysteresis.
The AM1611 is supplied with an ISO 17025 accredited calibration certificate.
This provides an important basis for traceable temperature calibration.
Reduced Immersion Errors
Short temperature probes present particular challenges because their sensing elements cannot always be positioned sufficiently deep inside a conventional dry well.
Insufficient immersion can result in significant temperature measurement deviations.
The Additel ADT 110 addresses this problem by improving the relative positioning of the reference probe and device under test.
The specially machined inserts allow both sensing elements to be located at similar depths.
This helps reduce errors caused by axial temperature gradients.
For calibration laboratories, this can improve measurement consistency and reduce the uncertainty contribution associated with sensor immersion.
However, the actual calibration uncertainty must always be evaluated for the complete measurement arrangement.
Efficient Calibration Without Liquid Baths
Liquid calibration baths are often used when calibrating short temperature sensors because they can provide good thermal contact around the sensing element.
However, liquid baths require additional maintenance and handling.
Calibration fluids must be selected according to the required temperature range.
They may also introduce contamination risks and require cleaning of the temperature probes after calibration.
The Additel ADT 110 Short Probe Calibration Kit provides an alternative for suitable applications.
When combined with a compatible Additel dry well calibrator, the kit enables short probe calibration without requiring a separate liquid bath.
This can reduce preparation time, simplify handling and improve the cleanliness of calibration procedures.
The result is a practical solution for laboratories seeking efficient temperature calibration workflows.
