ColorLite Densitometer sd350

The market leader for highest accuracy and precision  

Description

  • 2 Channel system measuring density values from 0.000 to 6.000 +/- 0.003 Reatability +/- 0,003 D at 3D
  • Measurement in transmission and optional reflection mode
  • LED light source – over 20 year life span
  • True grating spectrometer – over 100 sampling points in the VIS range
  • Solid aluminium integrating sphere as an ideal diffuse illumination source
  • Designed and “Made in Germany”

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 techniques. The device automatically recognizes which measurement technology is to be used.

Features

  • The ColorLite 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 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.
  • 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 by different users.

45/0° probe head – like the eye see´s it

The 45°/0° measuring geometry is standardised in DIN standard 5033. The sample is illuminated at an angle of 45° with a direct light source and the reflected light is measured at 0°. The Measurements of this measurement geometry come closest to the vis…

d/0° probe head – measuring inhomogeneity probes

The d/0° measuring heads ( and -adapters) MA38 and MA80 illuminate the sample with a diffuse LED light source on an area of 38 mm or an 80 mm respectively. These versions are used to measure inhomogeneous samples such as granules, food, wood paints or…
