This is a temperature and humidity meter with intrinsically safe explosion-proof construction that has passed the certification exam of the Industrial Safety Technology Association.
This device consists of a hygrometer main unit installed in hazardous locations and an insulating barrier installed in safe locations to maintain safety, outputting an analog signal of DC 4-20 mA for temperature and relative humidity. Additionally, the hygrometer main unit has an LCD display, allowing measurement values to be checked even in hazardous areas.
