NR-1 Color Checker

  • Compact, light-weight, battery-operated and simple operation.
  • It is equipped with the function of acceptance/rejection determination which is convenient for color difference measurements and use at production lines

Features

  • No calibration, and no warming-up time is required. It has one-touch operation to set a reference value for color difference and average the measured values
  • Film-formed target mark is very convenient when performing a partial measurement white locating a target point.
  • It has a sensor detecting a change in ambient temperature, which displays a warning message

  • You need not worry about whether or not you have turned off the power thanks to the energy saving design with automatic power-off function.

An Automatic Colorimeter Measuring Saybolt and ASTM Colour

The Lovibond PFX880/P is a high precision spectrophotometer for objective colour analysis of petroleum fuels, oils, waxes and petrochemicals according to the Saybolt and ASTM Colour scales. Results can also be displayed in terms of CIE values and spectral data. A factory fitted integrated heater unit for melting solid samples such as fats and waxes and preventing them from solidifying in the cell is also available

Colour Scales Scope Range

Colour Analysis made Simple

The Lovibond PFX880/P is an easy to use, automatic instrument, which eliminates time-consuming procedures of visual methods. There is no need to build up calibration curves as they are already established in the instrument. The menu system guides operators through the selection of operating parameters. Thereafter, measurements are initiated by just a single key press and take less than 25 seconds to complete.

Lovibond® Tintometer® Model F

Features :

The Model F is the latest in a distinguished series of Lovibond Tintometers which have been widely used for colour measurement in terms of Lovibond units for more than a century. The advance stems from the introduction of modern technology to enhance a traditional visual colorimeter.

  • Glass colour standards which are individually housed in durable, glass-filled nylon racks, affording excellent protection and allowing easy distinction between adjacent standards.
  • A prismatic optical system for improved colour matching accuracy and repeatability.
  • A balanced field of view with a sharp split line between sample and comparison fields to aid colour discrimination.
  • A diffused tungsten-halogen light source for standardised illumination.
  • A sample chamber liner which can be replaced at intervals to maintain the whiteness of the interior and includes a channel to ensure correct cell location and alignment.
  • An external, low voltage regulated power supply resulting in a cool-running instrument which can be left switched on.
