BL631 Liquid nitrogen comparison calibrator
Foam lid
User manual
Datasheet
The BL631 liquid nitrogen comparison calibrator is specially designed to calibrate standard platinum resistance thermometers (SPRT) and other temperature probes in extreme cold temperature. With the ability to calibrate up to 4pcs SPRT or 90pcs industrial sensors at a time it addresses capacity and flexibility needs for thermal calibration at cryogenic temperatures.
KEY FEATURES
Oxygen-Free High Conductance (OFHC)
Stainless steel dewar flask for safe operation and longevity usage.
Easy to use fill port allows for addition of liquid nitrogen as needed.
Foam lid included to reduce LN2 evaporation between calibrations.
Overall design ensures low evaporation rate and long lasting stable calibration points for many hours.
APPLICATION
Calibrate SPRTs, RTDs, various thermocouples and other probes by comparison with a reference thermometer.
Low temperature storage
