◆Special calibration equipment◆
Cryokelvin
Top load type refrigerator cryostat. Used to achieve any temperatures between-196°C and-80°C in JCSS calibration. The lower limit temperature can be achieved up to 20K(-253℃), and is also evaluated at liquid-hydrogen temperatures.
Liquid-helium tank 250L
The sensor is immersed in liquid-helium to evaluate 4K(-269℃).
Ultra-high-temperature thermocouple calibration furnace
Realizes 1100℃ to 2000℃. Type C we sell is used for lot-testing of tungsten-rhenium thermocouples (reference thermocouples are NIST traced).
