Temperature & Humidity Calibration Service

Our Temperature and Humidity Laboratory provides calibration services for a wide range of temperature and humidity measuring instruments, with temperature calibration capabilities from -35 °C to 1,200 °C.

The laboratory is equipped with high-accuracy reference standards and calibration equipment, including ASL Standard Platinum Resistance Thermometers (SPRT), ASL Platinum Resistance Thermometers (PRT), ASL Precision Digital Thermometers, non-contact thermometers, Standard Type S Thermocouple Probes, Water Triple Point Cells, Calibration Liquid Baths, Dry Block Calibrators, Data Loggers, and Temperature & Humidity Chambers.

These reference standards and calibration systems are used to calibrate temperature measuring instruments, including indicators, sensors, thermometers, probes, data loggers, and temperature & humidity meters / thermo-hygrometers.

Calibration is performed using comparison calibration methods with reference standards and simulation methods for compatible instruments.

Accredited calibration services are available for applicable instruments and ranges within our approved ISO/IEC 17025 scope of accreditation.
