The CL-500A Illuminance Spectrophotometer is our first hand held version of this instrument and is capable of measuring CRI and illuminance right on the unit. It’s completely stand-alone and turn-key. Simply turn it on, and start measuring.
The CL-500A can be used in a broad range of industries including lighting products manufacturing and lighting product design, where it’s important to measure CRI, color temperature and illuminance all at the same time.
Compact and easy to use, the CL-500A has a built in lithium battery which can be charged via a USB port.
In addition to spectral power distribution, this instrument is capable of measuring illuminance in foot candles or lux and chromaticity, excitation levels, dominant wavelength, color temperature and CRI.
It is important to calibrate the CL-500A every time before you use it. This is because when light sources is different or even small vibrations can cause discrepancies in measurements. Calibration helps ensure your readings are accurate.
The difference in distance between the sensor and light source can cause discrepancies in measurements, hence, it is important to document not only the distance but the angle between them to obtain accurate and consistent measurement data.
Multiple factors can influence the amount of light in a given space. Hence, for large area measurement, it is recommended to divide them into a grid and conduct measurement at each grid individually. After which, average all the measurement data to get the average illuminance in the area.
