The Thermo-Hygrometer MTH-1a is a modern, personal microprocessor device designed for air temperature and humidity measurement.

The Thermo-Hygrometer MTH-1a is a modern, personal microprocessor device designed for air temperature and humidity measurement. The MTH-1a can be used in mines and spaces where control of weather conditions is necessary. It has a small, lightweight & strong casing with a comfortable clip for portability. Air humidity is measured via HONEYWELL’s sensor and air temperature is measured via the integrated DS1820 sensor. Temperature and humidity values are displayed on LCD simultaneously. The device is battery-operated enabling an approx. 300 hours of continuous measurement. The battery is connected to an A/D converter which enables battery voltage control.
