AUTENS Digital Temperature Humidity Meter Color LCD Backlight measurement tool

Handheld Psychrometer for Field Use

The AUTENS digital temperature humidity meter combines humidity, temperature, wet bulb and dew point readings in one handheld unit. It targets HVAC engineers, facility managers and agricultural technicians who need simultaneous environmental data on site. A colour LCD with backlight presents dual values clearly in low light. Power comes from three AAA cells which are not supplied.

Battery Powered Operation With Auto Shutdown

The instrument runs on 3x1.5V AAA batteries and includes automatic shutdown to extend field life. No mains adapter or external sensor module is required, so the kit stays compact at 180x60x30mm and 190g. MAX, MIN, AVG and data hold functions let users capture peak conditions without a separate logger. Unit conversion switches between Celsius and Fahrenheit instantly.

Stable Accuracy Across Extended Sessions

Ambient temperature accuracy holds at ±1°C between 0 and 45°C and ±1.5°C from -20 to 0°C and 45 to 60°C. Relative humidity stays within ±3% across the 20% to 80% band, widening to ±4% at the extremes. Dew point and wet bulb figures follow the same tolerances, so sustained monitoring in machine rooms, wine cellars or data stores remains consistent over long periods.
