UNI-T UT383BT Mini Light Meter

The UNI-T UT383BT is a compact, affordable and highly accurate light meter that should be in every cactus cultivator’s toolkit. Why muck around and risk your prized collection or waste money on seeds that never sprout when this unit costs less than $50?

With a measuring range of 0 to 199,999 lux and a resolution of 1 lux, the UT383BT is highly accurate and provides precise readings that are critical for optimal cacti growth. It’s easy to use, with a backlit LCD screen that displays the current reading and a data hold function that freezes the reading on the screen. It also features a low battery indicator and an auto power-off function to help conserve battery life.

With Bluetooth connectivity, you can pair the device with the free UNI-T iENV App for real-time data visualization and analysis. Further to this, you can pair the device with a free third-party PPFD app to get PPFD and PAR values which are important for getting accurate measurements of LED grow lights and typically only possible with considerably more expensive light meters.
