PR-202 Lux Meter

PR202 Luxmeter measures light with the sensitivity of the human eye. It has an extensive range from few millilux to kilolux suitable for evaluating all illumination conditions.  It is highly rated because of the high precision and accuracy in measurements. It is portable, accurate and can be used for real-time monitoring of the luminaire as well as data logging using USB interface.



The light sensor has the responsivity of strict CIE standard observer curve V(λ). The cosine-corrected photodetector is designed specifically for use in museums, art galleries, as well as outdoor lighting designs where high degree of accuracy is demanded by lighting professionals.


It has a large LCD display that offers strain-free reading during the measurement. Display backlighting for easy readability during night time operation.

Data Transfer

Consists of Software that can be installed and a USB interface for visualizing real-time data as well as data logging for extended periods.


PR-212 Lux Meter is versatile that can provide accurate measurements from a few millilux to a few kilolux, thus suitable for both indoor and outdoor illumination measurement.  The optical grade acrylic diffuser provides cosine correction, so illumination can be made at any incident angles. The silicon photodetector is corrected to match wavelength sensitivity of the human eye.  A typical spectral response is shown here that matches with CIE V(lambda) function
