UNI-T UT333 is a digital temperature and humidity meter, designed for precise measurement of ambient conditions. The device will be suitable for both home and professional use - such as in warehouses, offices, greenhouses, server rooms, laboratories, etc. The UT333 measures temperature from -10°C to 60°C and humidity from 0% to 100% RH, with an accuracy of ±1°C and ±5% RH, respectively, making it accurate for most everyday applications. The unit's compact design, low weight (102 g) and backlit display make it handy and convenient to use, even in dimly lit areas.
Measurement range tailored to everyday needs
The meter can measure temperature from -10°C to 60°C (or 14°F to 140°F) with a resolution of 0.1°C/0.2°F and an accuracy of ±1.0°C/±2.0°F. Humidity measurement covers the full range from 0% to 100% RH, with a resolution of 0.1% RH and an accuracy of ±5% RH. These are sufficiently precise parameters to effectively control climatic conditions in rooms or equipment surroundings.
Practical functions to support daily operations
The UT333 offers useful functions: MAX/MIN modes allow you to keep track of extreme measurement values, Data hold keeps the current result on the screen, and the °C/°F switch makes it easy to customize the unit. A built-in overload (OL) alarm protects against erroneous measurements, and a backlit LCD screen allows operation even in low light conditions.
Compact design and economical power supply
The meter is powered by 3 AAA (R03) batteries, and its low weight - just 102 grams - and compact dimensions (155 × 50 × 28 mm) make the device comfortable to hold and fit easily into a bag, drawer or pocket. An automatic shut-off function after 5 minutes of inactivity helps save power, and a low battery indicator (3.0-3.5V) lets you know when it's time to replace it with a new one.
