The densitometer sd350 was developed to meet the high precision standards of the automotive industry. It measures density values of the color of a product, e.g. plastic films. The device is characterized by the highest quality and easy using.
A high dynamic range is ensured by the 2-channel system. Depending on the density of the film to be measured is measured with two separate measurement technologies. The densitometer automatically recognizes which measurement technology is to be used.
- The ColorLite densitometer sd350 is a transmission spectrophotometer which measures the spectral transmission curve in 3.5 nm intervals. From this data various density values are calculated using functions stored in the software.
- As the complete spectral transmission characteristics are measured, various colour metric data such as the CIE L*,a*,b*-values or Y, x,y chromaticity values can be visualised.
- Display of density values with true precise 3 positions after the decimal point.
- The illumination is created in a high quality integrating sphere (Ulricht-Kugel) that is produced on a CNC controlled lathe from a solid aluminium block. The sphere surface then goes through a coating procedure, with the final coats made of an ideal diffuse barium sulphate powder as described in the DIN 5033.
- By implementing the light source using an integrating sphere (as described in the DIN 4512-8) and a real grating spectrometer, the ColorLite sd350 measures the same results as elaborate laboratory equipment.
- Variable calibration warnings for zero and D3 calibration. Warning signal when the calibration intervals have been reached.
- By using our quality control PC software ColorDaTra emission curves for the sample film together with any light source can be calculated for reviews.
- Trigger threshold is automatically determined during the zero calibration. This accounts for variations of the sample thickness.
- Zero calibration to determine the offset value of the carrier materials.
- Calibration made using a certified BAM Density 3 glass filter.
- MSA Measurement System Analysis type 1 study passed automobile industry; Determining the repeatability (50 scans) on glass filters with values between D2 and D5.
- MSA Measurement System Analysis type 2 study passed automobile industry; Determining the reproducibility on samples with measurements being repeated and compare by different users.
