Portable Field Dry-Block/Wet Calibrator –（-50℃~140℃) – 0.2℃ AccuracyThe Low Temperature Dry Block Wet Calibrator ( 50 to +140) delivers consistent, precise, and uniform temperature settings with rapid stabilisation, making it highly efficient for both laboratory and field applications. Designed for portability and convenience, it is widely used for the calibration of temperature sensors, standard thermometers, thermocouples, thermal resistors, and dilatation thermometers. By eliminating slow heat up times and
