Ultra Low Temperature Dry Block/Wet Calibrator（-115℃~50℃)

The UCI-SL-AB-CAL Ultra Low Temperature Dry Block/Wet Calibrator (-115℃ to +50℃) provides precise, stable, and uniform temperature calibration for laboratory and on-site applications. Designed for portability and high efficiency, this calibrator allows rapid stabilisation and enhanced calibration speed, making it ideal for a wide range of temperature-measuring instruments, including temperature sensors, standard thermometers, dilatation thermometers, thermocouples, and thermal resistors.

The UCI-SL-AB-CAL solves common issues found in lower-end models, such as slow heat-up times and temperature inaccuracies, delivering faster calibration cycles and superior reliability. Its advanced heating principle ensures rapid heating, stable temperature holding, and quick cooling. Combined with high-precision sensors and touch screen operation, this model offers industry-leading calibration performance while meeting international standards.
