HCT-99D Light & Color Meter
A High Accuracy Light Measurement Tool
Compact, Portable & Easy To Use
Easily Measure LED & 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).

Field Service Applications
Check Site Results Quickly
The operation & qualification of light sources can be checked on site simply and repeatably for comparison and correlation to light and color measurements taken back in the laboratory.
Compare In-House Standards
It's also possible to coordinate the HCT-99D meter calibration to in-house color and illuminance standards by either self-programming of the meter for direct reading or by correction of the readings in spreadsheet using an Excel VBA (Visual Basic Application).
Manufacturing /
Production Applications
Practical QC Tool
The HCT-99D colorimeter is a practical quality control tool for establishing and maintaining lighting product specifications like color (x,y or u',v'), illuminance (lux), correlated color temperature standards in-house and in multi-national manufacturing operations.
Real Life LED Example
One example would be LED sorting and binning. The LED manufacturer or end-user may have a high level spectral color and light measurement system in their laboratory but doesn't want to duplicate this instrument in an international manufacturing facility due to the high cost and complexity of running a high-end spectroradiometric light measurement system.
Affordable Alternative
The HCT-99D is a low cost alternative to the high-end spectral measurement systems that can be self-calibrated or corrected to factory light and color standards if necessary.
Monitor Life Test Set-Up
Another example is light source monitoring in a life test set-up. Utilizing the HCT-99D USB interface, light and color measurements can be taken on any number of lamp stations using a USB hub with multiple light and color meters. The meter is powered via the USB interface so there's no problem with battery failure.
Lighting & Architectural Applications
Balance Light & Color Levels
Adding color and color temperature values to the classical photometric light measurement allows lighting engineers, architects and lighting designers to balance light and color levels for a more in-depth analysis of interior, exterior, landscape and accent lighting.
