In-ceiling light intensity sensors PHOTASGARD® DHKF I

Brand
€158.79
Tax included

The PHOTASGARD® DHKF light intensity measuring transducer supports six switchable measuring ranges (six devices in one). The sensor has been designed for installation in suspended ceilings. The connecting head is pluggable for quick and easy mounting. The measuring transducer is accommodated in a separate housing.

The sensor is specifically adapted to the sensitivity of the human eye. Its greatest sensitivity is in the range of 350 nm to 820 nm. With its special filter, the sensor is therefore ideally suited to exposure measuring of daylight and/or to measuring artificial light of high colour temperature (similar to sunlight).
