  UNI-T UT381A lux meter
The UNI-T UT381A lux meter is a reliable, safe and versatile device for measuring illuminance over a wide range (from 0 to 400,000 lux). Equipped with a probe with an integrated, separable and rotatable design, it provides maximum flexibility when working in different conditions. The device allows for data storage and also supports Bluetooth connectivity, making it easy to monitor and analyze results in real time. The UT381A also offers a color correction function (CCF) for even more accurate measurements. The product is CE and UKCA certified and supports multiple languages, including Polish, English, French, German, Italian, Spanish, Swedish and Czech.
Versatility in a variety of industries
The UNI-T UT381A is ideal for use in laboratories, offices, street lighting construction, retail, and other industrial and commercial applications. With its wide measurement range and built-in color correction function, the device provides accurate readings regardless of the type of light source. Multi-language support makes it easy for international teams to work together, and result storage allows for easy documentation and analysis of measurements over a longer period of time.
Practical design and convenience of use
Thanks to the advanced rotating probe, you can adjust the device's positioning to any situation, which greatly increases the comfort of your work. The lux meter allows you to view results on the display in real time, and the ability to connect to a Bluetooth app further streamlines data management.
