Uni-T UT331+ is a compact meter for fast and reliable monitoring of indoor and workplace climate conditions. It offers accurate measurement of temperature and relative humidity, calculation of the dew point and wet-bulb temperature, memory for up to 299 records, and USB data export for easy analysis on a PC.

The Uni-T UT331+ temperature and humidity meter is designed for everyday technical use, maintenance, and environmental condition checks. Thanks to a fast response time of about 1 second, it provides an instant overview of air conditions and helps identify condensation risk by measuring the dew point.

For greater control over results, the instrument enables offset calibration (temperature, humidity, dew point, and wet-bulb temperature). You will appreciate this during regular inspections and when more precise alignment with a reference measurement is required.

Memory for 299 measurements, together with automatic logging and MAX/MIN and Data Hold functions, makes longer-term monitoring easier without constant supervision. The backlit LCD improves readability and auto power-off saves battery.

Main advantages:

  • Temperature measurement in the range -20 °C to 70 °C
  • Humidity measurement 0–99.9 % RH
  • Dew point and wet-bulb temperature for a more comprehensive assessment of air conditions
  • 299-record memory and USB export to PC
  • MAX/MIN, Data Hold, alarm, and automatic saving

Package contents:
