The operating temperature must always be compatible with the selected calibration medium and accessories.
Two Calibration Methods in One Instrument
One of the main advantages of the europascal EP-MB-255 is its multifunctional design.
The instrument can be configured for two different temperature calibration methods.
Liquid Bath Calibration
In liquid bath mode, the temperature sensors are immersed in a suitable calibration liquid.
A magnetic stirrer circulates the liquid to improve temperature uniformity.
This method is particularly useful when calibrating sensors with different diameters or irregular shapes.
The liquid surrounds the immersed portion of the sensor and provides effective thermal contact.
Dry Block Calibration
In dry block mode, interchangeable metal inserts are used to accommodate temperature sensors.
The calibration block generates a stable temperature that is transferred to the inserted sensors.
Dry block calibration is particularly useful when a clean and convenient calibration process is required.
The ability to switch between these methods makes the europascal EP-MB-255 suitable for a wide variety of calibration tasks.
Excellent Temperature Stability
The europascal EP-MB-255 provides excellent temperature stability in both operating modes.
The manufacturer specifies:
±0.01 °C
This value applies to both liquid bath and dry block operation.
Temperature stability describes the variation of temperature over time under defined operating conditions.
Stable temperatures are essential for reliable temperature sensor calibration.
The low temperature variation helps reduce uncertainty contributions during comparison measurements.
For demanding calibration applications, sufficient stabilization time must be allowed before recording measurements.
High Temperature Accuracy
The europascal EP-MB-255 provides a specified temperature accuracy of:
0.1 °C
This accuracy specification applies to the instrument’s temperature generation and indication under the conditions defined by the manufacturer.
It must not be confused with temperature stability or the expanded measurement uncertainty stated on an individual calibration certificate.
For high-accuracy comparison calibration, an external reference thermometer may be used.
The reference thermometer measures the actual temperature in the calibration bath or insert.
The device under test can then be compared with the reference temperature.
Excellent Temperature Uniformity
Temperature uniformity is an important characteristic of temperature calibration equipment.
The europascal EP-MB-255 provides different uniformity specifications depending on the selected operating mode.
| Operating Mode | Temperature Uniformity |
|---|---|
| Liquid bath | ±0.03 °C |
| Dry block | ±0.05 °C |
The liquid bath provides particularly good temperature uniformity through circulation of the calibration liquid.
The dry block configuration offers a convenient alternative for sensors with suitable dimensions.
The selected method should depend on sensor geometry, required calibration uncertainty and operating conditions.
Liquid Bath Calibration with 0.6 Liter Capacity
The europascal EP-MB-255 features a liquid bath capacity of:
0.6 liters
The calibration chamber has a diameter of approximately 60 mm and a depth of 190 mm.
The liquid bath configuration is suitable for calibrating multiple temperature sensors.
The magnetic stirrer improves circulation of the calibration liquid.
This helps minimize temperature differences within the bath.
The stirring speed can be adjusted using a potentiometer.
The calibration liquid must be selected according to the required temperature range.
The manufacturer specifies suitable silicone oils with different viscosities.
Recommended Calibration Liquids
| Calibration Liquid | Specified Temperature Range |
|---|---|
| Silicone oil, 20 cSt | 7 °C to 220 °C |
| Silicone oil, 50 cSt | 50 °C to 270 °C |
The liquid must be compatible with the instrument and the intended calibration temperature.
The liquid manufacturer’s safety and operating instructions must also be followed.
Dry Block Calibration with Interchangeable Inserts
The europascal EP-MB-255 can also be used as a dry block temperature calibrator.
Interchangeable calibration inserts allow different sensor diameters to be accommodated.
The manufacturer specifies the following insert dimensions:
| Specification | Value |
|---|---|
| Insert diameter | 59.5 mm |
| Insert length | 165 mm |
| Temperature stability | ±0.01 °C |
| Temperature uniformity | ±0.05 °C |
Different insert configurations are available.
Examples include inserts for sensors with diameters of:
- 3.5 mm
- 4.5 mm
- 5.0 mm
- 5.5 mm
- 6.5 mm
- 8.5 mm
- 9.0 mm
- 9.5 mm
- 10.5 mm
Multi-hole inserts allow several temperature sensors to be calibrated simultaneously.
The appropriate insert should be selected according to the sensor dimensions.
Good thermal contact between the sensor and insert helps minimize measurement errors.
Adjustable Magnetic Stirrer
In liquid bath mode, the europascal EP-MB-255 uses a magnetic stirring system.
The stirring speed can be adjusted using a potentiometer.
The magnetic stirrer circulates the calibration liquid to improve temperature uniformity.
This is particularly important when several temperature sensors are immersed simultaneously.
The stirring speed should be adjusted to provide effective circulation without creating excessive turbulence.
Stable liquid circulation supports reliable comparison measurements.
Fast Heating Performance
The europascal EP-MB-255 provides efficient heating performance.
The manufacturer specifies a typical heating time of:
28 minutes from 30 °C to 220 °C
This allows the instrument to reach common calibration temperatures within a relatively short time.
Fast heating helps reduce waiting periods during multi-point calibration procedures.
Actual heating times depend on the selected operating mode, calibration medium and sensor loading.
Controlled Cooling Performance
The europascal EP-MB-255 also provides controlled cooling.
The manufacturer specifies a typical cooling time of:
30 minutes from 220 °C to 100 °C
This allows calibration procedures to be performed at several temperature points.
Cooling performance depends on the operating conditions and thermal loading of the instrument.
The temperature of the calibration medium must be monitored carefully before handling inserts or removing sensors.
Optional Infrared Calibration Insert
The europascal EP-MB-255 can be equipped with an optional infrared calibration insert.
This accessory allows the instrument to be used for certain infrared thermometer calibration applications.
The manufacturer specifies an operating temperature range of:
30 °C to 250 °C
The infrared calibration insert is designed for use with an external reference sensor.
This configuration can be useful when checking infrared thermometers and suitable non-contact temperature measuring instruments.
The achievable calibration uncertainty depends on the radiation characteristics of the insert, the measurement geometry and the infrared thermometer being calibrated.
Optional Surface Temperature Calibration Insert
An optional surface temperature calibration insert is also available.
The manufacturer specifies a temperature range of:
50 °C to 220 °C
This accessory is designed for calibrating suitable surface temperature sensors.
Surface temperature measurements are influenced by thermal contact, sensor pressure and heat conduction.
The appropriate calibration procedure should therefore consider these effects.
The optional insert extends the flexibility of the europascal EP-MB-255 beyond conventional immersion temperature calibration.
Calibration of Pt100 and RTD Sensors
The europascal EP-MB-255 is suitable for calibrating resistance temperature detectors.
Typical applications include:
- Pt100 calibration
- Pt1000 calibration
- Industrial RTD calibration

- Digital thermometer calibration
The temperature sensor is placed in the liquid bath or a suitable dry block insert.
The instrument generates a controlled temperature.
The indicated temperature of the device under test is then compared with a suitable reference temperature.
For demanding applications, an external reference thermometer is recommended.
Calibration of Thermocouples
The europascal EP-MB-255 can also be used for thermocouple calibration.
Thermocouples are widely used in industrial temperature measurement.
The instrument provides a controlled temperature environment for checking thermocouple measurement systems.
The thermocouple is inserted into the calibration bath or a suitable dry block insert.
Its indicated temperature can then be compared with the reference temperature.
For accurate thermocouple calibration, reference junction compensation and the uncertainty of the readout must be considered.
Dual Display and Intuitive Operation
The europascal EP-MB-255 features a dual temperature display.
The display allows users to monitor the calibration process conveniently.
The instrument provides a temperature resolution of:
0.1 °C
The user interface is designed for intuitive operation.
