BL631 Liquid Nitrogen Comparison Calibrator APPLICATION   Calibrate SPRTs, RTDs, various thermocouples and other probes by comparison with a reference thermometer. Low temperature storage The BL631 liquid nitrogen comparison calibrator is a device 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. The BL631 adopts internationally leading high vacuum insulation technology to achieve a highly stable calibration temperature field. Compared to traditional products, it is more stable and quite reliable. With a compact structure, the BL631 can reduce energy consumption and make lower noise, lower requirements for operating environment, and better performance in testing. It is suitable for use in calibration, military, electronic and electrical testing laboratories. 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.
