Lumetronics offers lumetron pm-3 digital lux meter that is a precision photometric instrument for research, lighting and photometric laboratories for illumination measurements. The meter is equipped with a state-of-the-art silicon photodiode detector with extremely linear characteristics. A multi-element colour glass correction filter to go with the detector response to the cie photopic curve has been specially designed by lumetronics after 4 years of in-house r&d. The display unit also possesses high linearity to optimise use of the precision detector. The manual display unit has a 3.5 digit lcd display, powered by a 9 v battery. Three ranges of the digital lux meter enable a measuring capability from 0.1 lux to 20,000 lux. A hold function freezes the displayed value when readings are taken in near inaccessible areas. The detector is housed in a standard 23 mm diameter housing and has cosine correction. Connection to the display unit is established through a precision swiss connector to ensure low noise.
