HCT-99D Light & Color Meter
A High Accuracy Light Measurement Tool
Compact, Portable & Easy To Use
Easily Measure LED and Standard Light Sources
Luminous Color & Illuminance (Lux) Light
Gigahertz-Optik's compact hand-held HCT-99D light and color meter provides fast, accurate incident color and illuminance (lux) light measurements of LEDs and standard type light sources in field service, production or research applications at an affordable price.
Easy To Use, Ergonomically Designed
The ergonomically designed HCT-99D meter is simple to use.
To measure, just connect the detector and switch on the meter. The HCT-99D's high contrast 4-line backlit LCD conveniently provides a simultaneous read-out of:
- Color chromaticity coordinates x,y and u',v'
- Illuminance in lux
- Correlated color temperature (CCT)
Color Difference Function
In the HCT-99D, a color difference function based on the calculation of delta uv is a standard feature. This is a color difference of the deviation of the measured x, y color coordinates from the black body radiator locus.
Precisely Adapted To CIE Functions
The HCT-99D includes the CT-4501-4 light and color detector head that houses four filter corrected detectors response precisely adapted to the CIE spectral tristimulus functions.
- Silicon photodiode based detection ensures a stable, linear and wide dynamic light and color measurement range with long lifetime.
- An extra Xshort blue spectral response detector improves accuracy when measuring high color temperature sources.
Calibrated & Certified To International Standards
The HCT-99D light and color meter is calibrated and certified to international standards backed by Gigahertz-Optik's EN/IEC/ISO 17025 accredited optical radiation calibration laboratory (Registration No. DKD-K-10601 - pdf download).
