PCE-CRM 40 Chroma Meter
Measurement range up to 150,000 lx / Measures correlated color temperature (CCT) / Standard chromaticity diagrams according to CIE 1931 and CIE 1976 / Indicates wavelength / Presents tristimulus and RGB values / Includes USB interface, cable and PC software

With the chroma meter or spectrophotometer PCE-CRM 40, important photometric factors in the field of light measurement can be determined. These include the tristimulus values of XYZ, the u´ and v´ color location coordinates according to CIE 1976, and the xy color location coordinates according to CIE 1931. Moreover, further color statistics are measured as absolute values and differences. The user can determine the dominant wavelength within the sensitivity range of the spectrophotometer, which is 360 … 780 nm, as well as the color density (Pe) and the correlated color temperature (CCT) in Kelvin.

Also, the spectrophotometer can measure the illuminance in lux (lx) or foot-candle (fcd) as well as the light flux in lumens (lm) and show the color location in the RGB color space. Due to the ergonomic single-handed operation, the large display, memory, data interface and software, measurements with the spectrophotometer can be carried out quickly and the results are reproducible. The test results can be recorded by means of the software. Its specifications make the spectrophotometer perfectly suitable to classify and optimize lighting installations and conditions in various fields of application.

- Illuminance measuring range: 0.1 ... 150,000 lux (lx) / 0.01 ... 15,000 foot-candle (fcd)
- Spectral wavelength range: 360 ... 780 nm
- Ideal tool for taking white LED color temperature measurements, as the device measures the chromaticity from the phosphor as well as inspects the light quality output from the assembled white LED
- Provides tristimulus XYZ values and RGB color space representations
- Identifies coordinates according to CIE 1931 and CIE 1976, with additional color metrics measured as
  absolute values ​​and differences
- LED ranking function
- Detachable receptor head allows for use in darkrooms or installation in inspection systems - requires optional cable (sold separately - see accessories tab for details)
- Calibration function
- Includes USB interface and cable for easy data transfer
- Comes with PC-compatible software for detailed data analysis via laptop or computer
- Takes correlated color temperature (CCT), illuminance, chromaticity, excitation purity, luminous flux, RGB and dominant wavelength measurements simultaneously
