The Cooke Corporation has introduced the cal-COLOR 400 Calibrated Precision Colormeter. The cal-COLOR 400 Colormeter provides fast and accurate measurements of color temperature, absolute chromaticity values and illuminance of light sources, and display areas.

The cal-COLOR 400 uses four silicon photodiode sensors with cosine correction to measure exactly like human eyes (Red, Green, Blue and Reference). The ergonomically designed angled sensor allows simultaneous measurement and readout without interference from the operator. The light sensor measures 20 mm and is angled 70º from the display face. The easy to read 46 x 30 mm LCD displays measuring units and battery diagnostics. It uses a 9 V Alkaline battery and offers 100 hours of life in the ON position and four years of life in the OFF position. Pressing the ON button twice easily changes user selectable units of fc or lux.

The cal-COLOR 400 Colormeter offers single button operation for ease of use. The colormeter is ideal for use in theatres, projection halls, retail displays, museum displays, film and television, etc. The colormeter is geared to architects, interior designers, facility manufacturers, lamp manufacturers, lighting designers, lighting specifiers, contractors, engineers and maintenance personnel.
