This handy battery-operated meter measures color and illuminance/luminance of light sources in the field or lab. The HCT-99-D measures color chromaticity coordinates x,y and u',v', lux, and candela per square meter, as well as correlated color temperature. The new Delta-UV function shows the deviation of the measured x,y color coordinates from the blackbody radiator locus. Other features include a high-contrast LCD with backlighting and computer control via a USB interface. Price: $2270. Gigahertz-Optik, www.gigahertz-optik.com.
