Labnics Dry Block Temperature Calibrator calibrates temperature sensors across 50°C to 650°C, with ±0.5°C accuracy and ±0.1°C stability. A high-conductivity alloy heat block distributes temperature uniformly, while automatic power adjustment regulates heating. Touchscreen control and one-key calibration support sensor testing. Manufactured for temperature sensor calibration and instrument verification in industrial, quality control, and research laboratories, this dry block calibrator supports temperature measurement validation.
