Color Measurement System ERX31 Laboratory instrument for the automotive industry. 45°c:0° geometry, DIN 5033, spectral measurement with high resolution, excellent interinstrument agreement and high long-term stability. Advantages of color measurement  Good correlation with average visual color difference perception (45°c:0° geometry) Excellent measurement results with real spectral resolution of 1 nm Good correlation of measurement results with the visual perception under all illuminants. Measurement area with 10 mm diameter Positioning aided by illuminating the target space, in particular for small samples Can also be used independent of the laboratory stand (portable) Excellent inter-instrument agreement with the proven ER 50 model (no longer produced) A little shorter and lighter than the ER 50 model

Functional description ERX31 The ERX31 is a compact, exact spectrophotometer for spectral measurement with the standardized geometry 45°circular / 0°. In both spectrometers the optical measurement signals will be separated into 401 different wavelength signals via corrected concave gratings and measured via photoelectric sensors (dispersed). Measurements are taken by an integrated photodiode line. The result is a true 1 nm spectral measurement resolution. The measurement signals will be amplified and digitized with high resolution. A fast processor calculates corrected spectral reflectance data....

Laboratory color measurement system ► Precise spectral color measurement The spectrophotometer ERX31 typically will be used in the laboratory with the laboratory stand EHX31 (see picture on front page), but also can be used mobile and hooked up by a 5 m cable. Even critical colors and demanding applications can be measured with high quality based on the excellent spectral resolution of 1 nm. The wide spectral range of the ERX31 from 330 nm to 730 nm gives excellent information. The sample illumination is similar to D65 and delivers very good measurement results in all wavelength ranges. ► Measurement...
