Description

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.

Features

• 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.
