Lovibond Gardner Comparator 3000

• Improved appearance and ergonomics.
• Constructed from ABS (Acrylonitrile Butadiene Styrene) Fire Retardant Plastic. This robust, chemically resistant material is ideal for industrial environments.
• Single press of large switch illuminates sample for one minute (two presses = two minutes, three presses = three minutes). So no energy and bulb wastage.
• Halogen, long life, light source combined with standard daylight filters ensures full compliance with old units and consistency from unit to unit.
• Low voltage power supply.
• Disk values read directly from disks.
• Disk can be simply, but securely, removed allowing replacement if necessary.
• A new replaceable white insert is included with each instrument to ensure correct lighting levels are
  preserved. The old models white painted internals often became contaminated and discolored over time.
• Packs of 3 white insert replacements can be ordered when needed (as with the current Model F instrument).
• As with the PFX and PFXi ranges, fully removable sample chamber allows quick cleanup of inevitable spillages.

The Gardner Color scales as specified in ASTM D1544 is a single number color scale for grading light transmitting samples with color characteristics ranging from light yellow to brownish red. It is widely used for oils, paint and chemicals, such as resins, varnishes, lacquers, drying oils, fatty acids, lecithin, sunflower oil, linseed oil, The scale is defined by the chromaticities of glass standards numbered from 1 for the lightest to 18 for the darkest.

The Lovibond® Gardner Comparator 3000 is a 3-field instrument for visually determining the Gardner Color of samples by direct comparison with colored glass standards. It incorporates the 18 glass standards which make up the scale in a pair of discs:
