Digital Lux Meter

Lumetron PM-3 digital lux meter from Lumetronics is a precision photometric instrument for research, lighting and photometric laboratories for illumination measurements. The meter features a state-of-the-art silicon photodiode detector with extremely linear characteristics. A multi-element colour glass correction filter to match the detector response to the CIE Photopic curve has been specially developed by Lumetronics after 4 years of in-house R&D. To optimise use of the precision detector, the display unit also has high linearity. The hand-held display unit has a 3.5 digit LCD display, powered by a 9 V battery. Three ranges provide a measuring capability from 0.1 Lux to 20,000 Lux. A hold function freezes the displayed value when readings are taken in hard to reach areas. The detector is housed in a standard 23 mm diameter housing and has cosine correction. Connection to the display unit is thtnugh a precision swiss connector to ensure low noise. Other photometric equipment such as integrating spheres, gonio photometers, alignment lasers, transmittance and reflectance test sets and a complete range of other test/measuring equipment and calibration services are available from the company.
