The environmental meter consists of a measuring sensor with handle, a wall bracket with a 1.5 m / 4.9 ft cable, a light transmitter and a digital display. The main application of this environmental meter lies in the continuous light measurement and light monitoring of photo labs and production areas, such as in food or drug manufacturing.

The digital display has a relay output for controlling alarm horns or flashing lights for visual or audible warning and a control output. The limit value for the alarm output can be programmed on the display. Likewise, the analogue output signal can be used to control window flaps or the signals of the transmitter can be stored, evaluated and documented on a logger. The sound warning device is very easy to connect and can be operated via 240V mains current.

The environmental meter XLT is designed for continuous measurement of the light intensity. The light transmitter and the digital display have standard dimensions and therefore fit into every control cabinet that has standard plug-ins. The environmental meter is particularly suitable for monitoring in companies that manufacture or store photosensitive materials, such as photo labs, food production/storage, and pharmaceutical production/storage.
