L-200 NEW!

Precision luxmeter

It is designed to measure the illuminance of natural and artificial radiation of point sources or scattered light. Each photometric laboratory should be equipped with such an excellent device. The connection of the proper adapter to the probe enables direct luminance measurement.

Class APC



The measurement set consists of the L-200 precision luxmeter and P-200 control unit or the L-200 precision luxmeter co-operating with PC via the RF-200C interface. The connection of the adapter turns the L-200 luxmeter into a luminance meter.


Very good spectral matching to the spectral sensitivity V( λ) and directional response to the cosine function guarantee the accuracy of illuminance measurement, regardless of the nature of the radiation. It does not require the use of any adjustment coefficients for different light sources. The advanced correction algorithms for the measurement result virtually eliminate the influence of temperature on the measured value.

Co-operation with PC

The P-200 control unit is equipped with the USB connector and micro SD memory card slot that make it easy to transfer measurement data to a PC. The RF200C software enables the processing of the measurement data saved there.
