Low temperature compact calibration unit KT-H503

The KT-H503 is a small and highly practical calibration device designed for temperature calibration of resistance thermometer and thermocouples.

Calibration possible from -100 to 50°C
KT-H503 using a Stirling refrigerator: -100℃ to 50℃
The use of a heat equalizing block significantly reduces lifting and lowering times.

Calibration possible from -100 to 50°C
A model with a calibration temperature range of -100 to 50°C that uses a Stirling refrigerator is available.
Shorten heating and cooling times
KT-H503 (-100 to 50°C type): 23°C to -100°C for approx. 40 minutes
Excellent stability and temperature uniformity
KT-H503 (-100 to 50°C type): ±0.03°C/30 min
Simple temperature setting
The quick switch button allows you to switch between eight pre-set temperatures.
Calibration report issued (option)
This device can be equipped with option Chino calibration certificate for the calibration device.
Issuance of JCSS calibration certificate (option)
We can issue JCSS calibration certificates based on the Measurement Act traceability system.
