Product information
UNI-T UT333S temperature and humidity meter
The UNI-T UT333S features a split-type sensor with a flexible spring-loaded cable, making it ideal for measurements in hard-to-reach places - such as air ducts, equipment interiors or corners of industrial installations. The UT333S is a useful tool both at home and in technical environments, where fast and precise readings of ambient conditions are important.
Accurate temperature and humidity measurements
The UT333S can measure temperature from -10°C to 60°C (or 14°F to 140°F) with a resolution of 0.1°C and an accuracy of ±1°C. Humidity measurement is possible over the full range from 0% to 100% RH, with a resolution of 0.1% and an accuracy of ±5% between 20-80% RH. Thanks to the high-sensitivity sensor, the device provides reliable data within just one second of switching on, making it fast and efficient for daily use.
Functionality and convenient operation
On the easy-to-read LCD display (32 × 35 mm), you can keep track of current measurement results, as well as check maximum and minimum values (MAX/MIN function). A built-in "data hold" function allows you to hold the reading on the screen, making it easier to work in tight or dark spaces. The UT333S also features a backlight, automatic shutdown of the device after inactivity, and an overload alarm to indicate when the measurement range has been exceeded.
Handy design and battery power
The meter is powered by three 1.5V (R03) batteries and weighs less than 310g. The compact housing, measuring 110 × 53 × 26 mm, makes the device fit easily in the hand or pocket. Thanks to the separate sensor connected by a spring-loaded cable, you can conveniently take measurements in remote locations without carrying the whole device.
