Cal-LIGHT Precision 400 Light Meter with NIST-Traceable Cal Cert

The ergonomic light meter features a silicon sensor with photopic and cosine correction for more precise illuminance measurements. The color meter provides fast and accurate measurement of color temperature, absolute chromaticity values, and illuminance of light sources; uses four silicon photodiode sensors (red, green, blue and reference) corrected to measure exactly like the human eye sees. Model 86535-00 features large backlit LCD as an option, and both meters include low-battery indicator and HOLD function to freeze display. Swing-out stand is ideal for fixed positions or tabletop measurements. What's Included: integral sensor, integral stand, NIST-traceable calibration certificate supplied by the manufacturer, carrying case, and one 9 V battery Angled integral sensor allows simultaneous measurement and readout without interference from operator
