Product overview

The Comparator 2000 platinum-cobalt series provides visual Pt-Co/Hazen/APHA grading of clear, lightly yellow liquids. Four configurations cover 0–70, 10–250 or 0–250 mg Pt/L with different Nessleriser path lengths.

Key features

  • An integrated prism brings the sample and comparison fields together for colour discrimination; ultrasonic sealing protects the optics.
  • Calibrated glass standards represent discrete, colour-stable grades for direct sample matching.
  • Choose the 113, 250 or 288 mm path length for the required pale-liquid range; use the discs, Nessleriser and lighting unit specified for each model.
  • The supplied Daylight unit provides consistent illumination and reduces the influence of changes in ambient lighting.
