This makes the europascal EP-MB-165 particularly suitable for calibrating temperature sensors used in refrigeration systems, environmental monitoring, pharmaceutical manufacturing and industrial temperature measurement.
Multifunction Liquid Bath and Dry Block Calibrator
One of the most important advantages of the europascal EP-MB-165 is its multifunction design.
The instrument combines two temperature calibration methods in a single device.
Liquid Bath Calibration
In liquid bath mode, the instrument uses a temperature-controlled calibration liquid to provide excellent thermal contact with inserted temperature sensors.
This method is particularly suitable for calibrating sensors with different diameters, shapes and sensing element positions.
The liquid bath provides excellent temperature uniformity and stable measurement conditions.
Dry Block Calibration
In dry block mode, interchangeable metal inserts provide controlled temperature conditions without requiring a calibration liquid.
This method is particularly suitable for routine calibration, field service and industrial maintenance.
The dry block configuration simplifies handling and reduces preparation and cleaning requirements.
The ability to switch between both methods makes the europascal EP-MB-165 a flexible solution for demanding calibration applications.
Excellent Temperature Stability of ±0.01 °C
The europascal EP-MB-165 provides excellent temperature stability in both operating modes.
The specified temperature stability is:
±0.01 °C
This applies to both liquid bath and dry block operation.
Temperature stability describes the variation of the calibration temperature over time under defined operating conditions.
High temperature stability is essential for accurate comparison calibrations.
It helps minimize measurement variations and supports reliable calibration results.
For demanding calibration applications, the stability contribution must be considered when evaluating the measurement uncertainty.
High Temperature Accuracy
The europascal EP-MB-165 provides a specified temperature accuracy of:
0.1 °C
The instrument uses an internal reference temperature sensor to control and monitor the calibration temperature.
This allows accurate temperature generation across the specified operating range.
For applications requiring particularly low measurement uncertainty, a calibrated external reference thermometer can be used.
The external reference thermometer measures the actual temperature within the calibration bath or dry block insert.
This enables direct comparison between the reference thermometer and the device under test.
The measurement uncertainty of the complete calibration system must be evaluated according to the applicable calibration procedure.
Excellent Temperature Uniformity
The europascal EP-MB-165 provides excellent temperature uniformity.
The specified values depend on the selected operating mode.
