The rental-only L203 photometer is a high performance portable instrument designed to measure a wide range of illuminance levels. They are calibrated directly in Lux (Lumens per square metre) using a high accuracy photopic filter to give the user confidence in the veracity of the measurements from light sources with different spectral distributions.
The model L203-Lux is available for illuminance measurements only.
Features
The photometers comprise of a hand held display unit, a detector / amplifier assembly with connecting cable, an illuminance filter ring and a luminance field of view probe. The sensor is a large area silicon photodiode with excellent linearity and long term stability. The Irradian photopic filter ring and photopic field of view probe, fitted to the front of the silicon detector give a response which closely matches the human eye response outlined by the CIE Vl curve. This precise colour correction gives high accuracy of photometric measurements from light sources with different spectral distributions
