KF-10

Photometric calibrator

The KF-10 photometric calibrator is a high-stability light source used for periodical metrological control of luxmeters.

 

Reliability of measurements

The calibrator is intended for periodical metrological control of luxmeters made by SONOPAN. The regular use of the calibrator enables an early detection of the possible deficiencies of the luxmeter measurement circuit, which ensures the accuracy of the obtained results of the measurements.

ATTENTION: the control of the luxmeter with the use of the KF-10 photometric calibrator does not replace calibration.

Outstanding stability

The optical system of the illuminator and electronic control of light source operation guarantee the high stability of the luminous flux density in time.
