Temperature calibration for sensors, thermometers and controllers
Temperature is the most measured quantity in most facilities, and one of the easiest to get wrong. We calibrate the sensors, indicators and controllers you rely on against traceable temperature standards.
How temperature calibration works
Temperature sensors age. Thermocouples drift with heat cycling, RTDs change with mechanical stress, and indicators and controllers can shift after service. The result is a process, fridge or oven running hotter or colder than the display suggests.
We use the comparison method: the instrument under test and a reference probe are placed in a stable heat source, such as a dry-block calibrator or liquid bath, and readings are compared at several temperatures across the working range.
The same approach applies to digital thermometers used in laboratories and hospitals, and to the temperature loop of equipment such as incubators and ovens. For equipment-level checks, see Laboratory Equipment Calibration.
Small temperature errors, big consequences
Product quality
Sterilisation, drying, curing and storage all depend on reaching and holding the right temperature.
Safe storage
Vaccines, blood, reagents and samples need cold storage that really is at its set point.
Energy and cost
A controller that overshoots wastes energy; one that undershoots risks rejected batches.

Where temperature calibration is needed
How the work is carried out
Range and points
We agree the temperatures that matter for how each instrument is used.
Comparison
Instrument and reference are compared in a stable heat source at each point.
Adjustment support
Where the instrument allows it, offsets are corrected and re-checked.
Certificate
Results, uncertainty and status are documented for each instrument.
