UNI-T UT333S – Digital temperature and humidity measuring device with data logging function
UNI-T UT333S is a high-precision digital hygrometer for measuring air temperature and relative humidity, designed for use in industrial, warehouse, laboratory and everyday home environments. Equipped with the function of data logging (Data Logging) and measurement statistics (MAX/MIN/AVG), it is an evolved version of the popular UT333 model.
Precise temperature and humidity measurement – in real time
The UT333S enables fast and stable measurement of:
- ambient temperature in Celsius or Fahrenheit,
- relative humidity (RH) in the range of 0% to 100%.
High-quality sensors enable operation even under changing conditions – with high accuracy, regardless of ambient temperature or humidity.


Extended functions – statistics and data logging
The UT333S offers the user much more than just measurement:
- HOLD function – stopping the current reading,
- MAX/MIN/AVG – recording of maximum, minimum and average values,
- Data Logging – automatic storage of results for later analysis,
- Backlit LCD display – convenient readings even in dark environments,
- Fast sensor response – immediate information about changes in conditions.
These features make the UT333S an ideal tool for continuous monitoring of the working environment, e.g. in warehouses, greenhouses, server rooms, archives or museums.
