UNI-T UT383S digitálny luxmeter s MAX/MIN/AVG, podsvietením, automatickým vypnutím

Unlike typical lux meters, the UNI-T UT383S combines a wide 0–199,900 Lux measurement range with a compact, handheld design and one-button switching between Lux and Foot-candle units. Its silicon photodiode sensor with CIE photopic spectral response filter ensures readings closely match human eye perception, making it ideal for lighting professionals, photographers, and facility managers who need reliable illuminance data on the go.

Highlights

• Wide measurement range: 0–199,900 Lux / 0–19,990 FC
• High accuracy: ±(4%rdg + 8dgts) below 10,000 Lux, ±(5%rdg + 10dgts) above
• MAX/MIN/AVG recording modes for trend analysis
• Data hold, backlight, and auto power off (5 min) for convenient field use
• Powered by 3 x AAA batteries (included), low battery indicator

In daily use

The UT383S is built for quick, one-handed operation. The 4-digit LCD is easy to read even in dim environments thanks to the backlight, and the sampling rate of 2 times per second delivers responsive updates. Use the MAX/MIN/AVG modes to capture peak or average lighting levels in a room, or freeze a reading with data hold. The meter automatically powers off after 5 minutes of inactivity to conserve battery life.
