Konica Minolta CL-200A Illuminance Colorimeter

Gives accurate illuminance & colour readings - even with LEDs!

The CL-200A is an affordable, portable, tristimulus colorimeter that provides accurate readings regardless of the type of light source under test - even with LEDs!. The CL-200A is used for measuring the illuminance (luminous flux received per unit area), chromaticity, colour temperature and dominant wavelength of light sources in lux (or foot candles, where 1 fcd = 1 lumen per square foot = 10.764 lux). Don't confuse affordability with inaccuracy, though. The CL-200A is equipped with advanced features which promote measurement accuracy and ease of use. The spectral response of the CL-200A's three silicon photodiodes is matched closely to the CIE tristimulus observer functions using special filters, while a cosine diffuser ensures that the effective illuminance from off-axis sources is scaled correctly. The CL-200A provides measurements over 4 decades, from 0.1 to 99,900 lux (colour readings require 5 lux or higher). In nature, illuminance typically ranges from about 0.01 lux on a dark night to about 100,000 lux on a hot summer day. Workplace illumination is normally around 1000 lux.

Flexible & Convenient

The CL-200A conveniently allows you to separate the sensor head from the main body of the meter. This allows you to hold the sensor towards the light source whilst standing to one side and reading the light level. To use the CL-200A  in this way, you will need to order a couple of optional accessories (T-A20 receptor unit for the main body and the T-A21 receptor unit for the sensor head with 1m LAN cable).

Many Advanced Features

Basic operation of the CL-200A gives you readings of the illuminance in lux (or you can select foot candles if you prefer), chromacity as CIE xy or u'v' coordinates, correlated colour temperature (CCT) in Kelvin and dominant wavelength (in nm). The CL-200A also reports the tristimulus values XYZ and colour differences. Advanced operation allows you to hold a reference reading and enter colour correction factors specific to the type of light source under test. The CL-200A features as standard a USB interface - software is provided that allows you to log readings to an Excel spreadsheet. Zero adjustment is automatic, while you can either leave the meter to set its own range automatically or choose your preferred range manually. The LCD display features a backlight that turns on automatically under low ambient illumination. The CL-200A operates as standard from AA-size batteries (non-rechargeable), while an AC mains adaptor is available as an accessory.
