PCE-CRM 40 is a portable handheld lux meter used to accurately measure the correlated color temperature (CCT - in Kelvin), illuminance, chromaticity, excitation purity (Pe), luminous flux (in lumens - lm), RGB and dominant wavelength of light sources such as LED, organic LED (OLED) and other forms of organic electroluminescence (EL).

• Measuring range: 0.1 … 150,000 lux / 0.01 … 15,000 foot-candle
• Spectral wavelength range: 360 … 780 nm
• Display: 3.2" colour LCD
• Chromaticity: Ev xy, Ev u'v'

The lux meter consists of a measuring sensor with a handle and a wall bracket with a 1.5 m (4.9 ft) cable, a light transmitter and a digital display. The main area of application of the lux meter is in the continuous light measurement and light monitoring of photo laboratories and production rooms (e.g. food or drug production …).

• Measuring range: 0 … 50000 lux in three areas
• Resolution: 0.1 lx / 1 lx
• Accuracy: ±5% of reading
• 4 to 20-mA analog output
