PR550 Portable Liquid Calibration Bath: -30°C to 300°C wide temperature range, 0.1°C temperature control accuracy. Designed for rapid calibration of industrial field sensors and laboratory instruments. Get technical solutions now.
The PR550 Series Portable Liquid Calibration Baths while nearly identical in the compact size and weight to conventional dry block calibrators, combine the advantages of liquid thermostatic bath - such as superior uniformity, large heat capacity, and exceptional resistance to environmental interference, with excellent static and dynamic temperature control characteristics. PR552B/PR553B models feature integrated full-function temperature measurement channels and standard instrument measurement channels, supporting editable calibration tasks. This enables fully automated on-site calibration of thermocouples, RTDs, temperature switches, and electrical-output temperature transmitters without external devices.
