Temperature Range from −100 °C to +400 °C
The europascal EP-E182 provides a wide temperature measurement range from:
−100 °C to +400 °C
This temperature range makes the reference thermometer suitable for numerous industrial and laboratory applications.
Typical measurement and calibration temperatures include:
- −100 °C
- −80 °C
- −50 °C
- 0 °C
- +50 °C
- +100 °C
- +150 °C

- +300 °C
- +400 °C
The wide operating range allows the EP-E182 to be used with different temperature calibration sources.
These include dry block calibrators, liquid calibration baths and calibration furnaces.
The appropriate temperature source should be selected according to the required calibration temperature and measurement uncertainty.
For demanding calibration applications, sufficient immersion depth and thermal stabilization must be ensured.
High-Precision Pt100 Sensor
The europascal EP-E182 uses a high-quality platinum resistance thermometer.
The nominal resistance is:
100 Ω at 0 °C
The resistance at 0 °C is specified as:
R₀ = 100 Ω ±0.05 Ω
The temperature coefficient is:
α = 0.003850 ±0.000005 Ω/Ω/°C
The sensor characteristics are based on IEC 60751:2008.
The platinum resistance element provides a predictable relationship between temperature and electrical resistance.
This makes Pt100 sensors particularly suitable for precise temperature measurements.
When the temperature changes, the resistance of the platinum element changes accordingly.
A compatible resistance thermometer readout measures this resistance and converts it into a temperature value.
For high-accuracy measurements, the individual calibration characteristics of the reference thermometer should be considered.
1/10 DIN Tolerance
The europascal EP-E182 uses a highly stable Pt100 detector with a tolerance specification of:
1/10 DIN
This tolerance describes the permitted deviation of the sensing element from its nominal resistance-temperature characteristic.
The detector is designed for applications requiring higher precision than conventional industrial Pt100 sensors.
The 1/10 DIN designation must not be confused with the uncertainty stated on an individual calibration certificate.
The actual measurement uncertainty depends on the sensor calibration, measurement electronics and operating conditions.
For demanding reference measurements, an individual calibration of the complete thermometer is recommended.
Excellent Long-Term Stability
One of the most important characteristics of the europascal EP-E182 is its excellent long-term stability.
The manufacturer specifies a typical annual drift of:
2.5 mK
This corresponds to:
0.0025 °C per year
Low long-term drift is particularly important for reference thermometers.
It helps maintain reliable measurement performance between regular calibrations.
The EP-E182 uses highly stable and annealed platinum detectors.
The annealing process helps improve the stability of the sensing element.
Actual long-term drift can depend on operating temperature, thermal cycling, mechanical stress and handling.
Regular recalibration is recommended to monitor the stability of the thermometer.
Four-Wire Measurement Technology
The europascal EP-E182 uses a four-wire connection.
Four-wire resistance measurement is particularly important for high-precision Pt100 temperature measurement.
In a conventional two-wire measurement, the resistance of the connecting leads contributes directly to the measured resistance.
This can cause significant temperature measurement errors.
With four-wire technology, separate current and voltage connections allow the resistance of the sensing element to be measured with substantially reduced influence from the connecting leads.
This improves measurement accuracy.
The EP-E182 can be connected to suitable precision resistance thermometer readouts supporting four-wire Pt100 measurements.
The electrical connector can be selected according to the required configuration.
Slim Sensor Design
The europascal EP-E182 features a particularly slim sensor construction.
The sensor diameter is:
4 mm
The sensor length is:
200 mm
The compact design allows the reference thermometer to be used in applications with limited space.
This is especially advantageous when using dry block temperature calibrators.
Many dry block calibrators have relatively narrow calibration holes.
The small sensor diameter allows the EP-E182 to be inserted into suitable calibration inserts.
The slim construction also makes the thermometer suitable for comparison measurements involving several temperature sensors.
Compact Handle
The europascal EP-E182 features a compact handle.
The handle dimensions are:
12 mm diameter × 40 mm length
The small handle allows the thermometer to be used in confined spaces.
This is particularly useful when calibrating sensors in compact dry block calibrators.
The handle also provides a convenient transition between the metal sensor sheath and the connecting cable.
The thermometer should be handled carefully to avoid mechanical stress on the sensor and cable.
Highly Stable Detector
The europascal EP-E182 uses a highly stable, annealed platinum detector.
The sensing element has a length of:
25 mm
The detector is designed for accurate temperature measurement and excellent long-term stability.
The position and length of the sensing element are important when selecting the required immersion depth.
For accurate measurements, the complete sensing element must be exposed to a sufficiently uniform temperature.
Insufficient immersion can cause measurement errors due to heat conduction along the sensor stem.
The required immersion depth depends on the temperature difference between the measuring environment and ambient conditions.
Low Self-Heating
The europascal EP-E182 is designed for precision resistance measurements.
The recommended measuring current is:
1 mA
The manufacturer specifies a self-heating value of:
4 mK
Self-heating occurs because electrical power is dissipated in the platinum sensing element during resistance measurement.
This can cause the sensor temperature to rise slightly above the temperature of the surrounding medium.
The magnitude of self-heating depends on the measuring current and thermal conditions.
For demanding calibration applications, self-heating should be considered in the measurement uncertainty evaluation.
Using a suitable measuring current helps minimize this influence.
Low Thermoelectric Voltage Connection Cable
The europascal EP-E182 features a specially designed connecting cable.
The cable uses low thermoelectric voltage stranded wires.
This helps reduce unwanted thermoelectric effects in precision resistance measurement circuits.
The thermometer wires are made of silver.
The standard connecting cable length is:
1 m
Different electrical connection configurations are available.
The appropriate connector should be selected according to the resistance thermometer readout.
Configurable Design
The europascal EP-E182 can be configured according to individual measurement requirements.
Different electrical connections can be selected depending on the intended application.
This allows the thermometer to be integrated into existing calibration systems.
The slim sensor design makes it suitable for different temperature calibration sources.
The configuration should be selected according to the required temperature range, measurement electronics and calibration procedure.
europascal can assist with selecting a suitable configuration for professional temperature measurement applications.
Calibration in Dry Block Calibrators
The europascal EP-E182 is particularly suitable for use as a reference thermometer in dry block calibrators.
A dry block calibrator generates a controlled temperature within a metal calibration block.
The reference thermometer is inserted into a suitable calibration hole.
The temperature indicated by the reference thermometer can then be compared with the temperature indicated by the device under test.
The slim 4 mm sensor diameter allows the EP-E182 to be used with many calibration inserts.
For accurate comparison measurements, the reference thermometer and device under test should be positioned at suitable immersion depths.
Temperature stability, axial temperature distribution and radial temperature differences must be considered.
Calibration in Liquid Baths
The europascal EP-E182 can also be used in liquid calibration baths.
Liquid baths provide a controlled temperature environment for comparison calibration.
The reference thermometer and device under test are immersed in the calibration liquid.
After sufficient stabilization, their temperature indications can be compared.
Liquid baths are particularly suitable for calibrating sensors with different geometries.
The EP-E182 can serve as a reference thermometer within its specified temperature range.
The calibration liquid and immersion arrangement must be suitable for the selected temperature.
Calibration at ITS-90 Fixed Points
The europascal EP-E182 can be calibrated using temperature fixed points according to ITS-90.
ITS-90 is the International Temperature Scale of 1990.
It provides a framework for realizing and disseminating temperature values using defined fixed points and interpolation procedures.
According to the europascal product documentation, the company’s resistance thermometers can be calibrated at ITS-90 fixed points.
This supports metrological traceability.
The calibration procedure and available fixed points depend on the required temperature range and calibration scope.
The individual calibration certificate documents the calibration results and associated measurement uncertainties.
DAkkS-Accredited Calibration
The europascal EP-E182 can be calibrated in the DAkkS-accredited calibration laboratory of europascal.
DAkkS-accredited calibration provides documented metrological traceability to national and international measurement standards.
The manufacturer documentation describes two calibration methods.
Fixed-Point Calibration
Calibration can be performed using ITS-90 temperature fixed points.
Comparison Calibration
Calibration can also be performed by comparison in liquid calibration baths and calibration furnaces.
For comparison calibration, the datasheet specifies measurement uncertainties from:
10 mK to 40 mK
The applicable uncertainty depends on the temperature and calibration conditions.
These values describe calibration capability under specified conditions and are not a general accuracy specification for every measurement with the thermometer.
