3 fields colour measurement according to ASTM D1500 colour scale

The new Comparator 3000 / AF 650 Petroleum Oil Comparator (POC) is an enhanced model of previous Lovibond® instrument, which combines strength points of both previous instruments with new significant benefits:
  • Improved appearance and ergonomy
  • Made of fireproof ABS plastic (Acrylonitrile Butadiene Styrene). This sturdy and chemically resistant material is ideal for industrial facilities.
  • A single pressure of the big actuator lights the sample for a minute (two pressures = two minutes, three pressures = three minutes). So no energy and lamp waste
  • The halogen long-life light source, combined with standard filters for daily light, assures complete compliance with the previous units and consistency from a unit to another
  • Low voltage supply source
  • On disk values directly read from disk
  • The disk can be easily removed, safely, allowing for its substitution, if necessary.
  • A new white replaceable insert is included with each instrument, to assure that right light levels are preserved
  • When necessary it is possible to order packages with 3 white spare inserts
  • The easily removable sample chamber allows for a fast cleaning of unavoidable spillovers
A single scale and 3 fields instrument for a visual colour measurement by direct comparison between the sample and the Lovibond® glass colour standards, housed in a disk pair. The benefit of a 3 sections visual field is that the sample and two consecutive glasses on the colour scale are simultaneously displayed, allowing to easily reach optimal colour matching. For a fast colour measurement between predetermined colour limits, glass standards can be set at two limiting colours, so that to easily check if the sample is within the tolerance. The tungsten halogen light source is corrected for the colour with the standard CIE C illuminant, which guarantees constant lighting conditions for colour measurement.
The samples are measured in clear glass tubes 10.65 mm in diameter.
