LPPHOT03… Series – Photometric Probes for Illuminance

Login to see prices In Stock Sold out

The probe LPPHOT03 measures illuminance (lux), defined as the ratio between the luminous flux (lumen) passing through a surface and the surface area (m²). The spectral response curve of a photometric probe is similar to the human eye curve, known as standard photopic curve V(λ). The difference in spectral response between LPPHOT03 and the standard photopic curve V(λ) is calculated by means of the error f'1.

Calibration is carried out by comparison with a reference luxmeter, calibrated by a Primary Metrological Laboratory. The Calibration Procedure complies with the CEI publication No.69 “Methods of characterizing illuminance meters and luminance meters: Performance characteristics and specifications, 1987”.

The photometric measurement probe is designed for outdoor readings. CIE photopic filter.

Output, according to the chosen configuration, in mV or 4…20 mA or 0…10 Vdc normalized output or RS485 MODBUS-RTU output.

  • LPPHOT03 = mV / klux
