Bench-top Spectrophotometer CM-3700A

The standard for basic colour QC in a range of industries.

Konica Minolta Chroma Meters have a long heritage for offering organisations cost effective, traceable colour quality control measurements.

The CR-400 has an 8 mm measuring area, suitable for measuring reflected colour and colour difference in a wide range of industrial fields. It is widely used for colour QC in various applications including ingredients, foods, raw materials and finished products.

If samples are structured or uneven in surface, such as granulates, fabrics, wood, stones, bricks, then the CR-410 is the right choice. The unique large aperture (50 mm) is ideal for such samples where the operator would otherwise need to manually average several measurements to obtain representative and repeatable data.

Features

Features
A tristimulus chroma meter measures colours using filters that match the cone cells in the human eye. As these instruments use filters that closely match the spectral sensitivity of those cells, they correlate with a typical human observer, providing traceable measurement data for the sample under standard illuminant D65 and C.
 
  • Vertical alignment: ergonomically designed grip and vertical alignment provides stable contact to samples, allowing measurement of samples with small or difficult contours.
 
  • 8mm or 50mm measurement aperture: whether your sample is homogeneous or inhomogeneous, selecting the instrument with the correct measurement aperture will provide consistent and repeatable results.
 
  • External data processor and thermal printer: configure the device on the move and conveniently / quickly produce colour data labels for samples or batches. The DP-400 data processor offers improved versatility, essential when not connected to a PC with colour data software.
 
  • Battery or AC power: power the instrument either via AC cable or AAA batteries in order to minimise downtime.
 
  • Simple colour, colour difference and tolerance data: Simple black and white backlit LCD displays relevant measurement data or simplified Pass/Warn/Fail based on operator defined tolerances. 
 
  • Precision accessories: maximise repeatability and ease of sample presentation with purpose built accessories for powders, beans and opaque liquids.
