The Lux Meter LXT consists of a measurement sensor and a small wall bracket or holder with a 1.5 m cable, and a light transmitter. The application field of the Lux Meter LXT is the continuous measurement of daylight and light control in photo labs and production facilities, such as in the manufacturing of food and medicine. The digital analogue output of the Lux Meter LXT can be used to control valves or to save the signals from the transmitter in a data logger, to assess and document them.
