Mining HygroMeter

Mining hygrometers detect the air temperature and moisture content in mines through sensors, converting physical quantities into electrical signals for display. They are used to monitor underground environmental conditions, prevent equipment corrosion, and ensure operational safety. They are employed in real-time monitoring within mining tunnels and ventilation systems.
Selection
When selecting, ensure the explosion-proof certification level matches the mine type, and the measurement range covers -10℃ to 50℃ and 0-100% RH. The housing should be sturdy and corrosion-resistant, with a probe resistant to dust interference. Prioritize models with digital display and alarm functions, and perform regular calibration and maintenance to ensure data accuracy.
