The device uses a precision digital sensor and an 8-bit microprocessor for data processing, thanks to which it has a high sampling rate of 100 / s, a built-in real-time clock and a memory for storing 2044 measurements. The measuring range is from 0 Lux to 20000 Lux in four subranges. Measurements can be performed at preset intervals. The low power consumption of the UT381 luxmeter allows up to 200 hours of continuous operation on a 9V alkaline battery (6LF22). It is possible to select automatic switch-off after approx. ten minutes.
