LuxCal250 Lux and Luminance Meter Calibration

The LuxCal250 provides accurate luxmeter calibration over an exceptionally wide dynamic range.

lux cal250

Comprising a light-tight enclosure housing standards of illuminance, Bentham’s LuxCal250 presents a straightforward and cost-effective calibration solution obviating requirements typical of traditional, distance-based calibration.

Designed as a high-performance, all-in-one calibration solution, the capabilities of the LuxCal250 may be extended to encompass precise luminance meter calibration with the LumiCal50, alongside representing a UKAS accredited calibration device with the LuxCal .

Based on an exceptionally stable, colour-filtered quartz tungsten halogen lamp, the output levels are varied via neutral density filters, providing a range of calibration levels. The LuxCal250 and LumiCal50 are both calibrated in our dedicated laboratory with respect to standards calibrated by Physicalish Technische Bundesanstalt (PTB, Germany).
