Calibrate temperature

The E+E accredited laboratory perform calibrations of temperature measuring devices in the air for the range -40 to 180 °C (-40...365 °F) as well as in dry block calibrators for the range -45 to 425 °C (-49...797 °F).

The E+E on-site service is available for accurate calibration of stationary systems such as furnaces, climate chambers, refrigeration and freezer cabinets.

Calibration procedure

The calibration is performed for air temperature sensors in a temperature-stabilised measurement chamber at a gas flow of 5 l/min, for contact thermometer in a block calibrator with high precision temperature regulation. The generated temperature is determined using a calibrated Pt100 resistance thermometer and used as a reference value.
