APHA/PT-Co 

Platinum-Cobalt Color Analyzer System

Reliable Color Analyzer (ASTM D1209)

The Smart, Cost-Effective Choice

Using our APHA/Platinum-Cobalt Color Analyzer System to automate this measurement within a process eliminates the visual judgment of a technician and delivers online real-time process control information to the process operators.

The APHA/Platinum-Cobalt Color Analyzer System utilizes our multi-wavelength ClearView db filter photometer analyzer platform. It may be configured for either one (1) or two (2) independent sample monitoring points. The ClearView db analyzer is configured with application-appropriate wavelengths to measure the APHA/Platinum-Cobalt color of the sample. The analyzer employs a dual-beam design – meaning; the system has an continual internal optical reference check that allows it to self-compensate for signal variation due to non-sample conditions. This ultimately provides the system with long term stability. The final product is a total APHA/Platinum-Cobalt Color System that measures the color variation without interference from other factors.

The APHA/Platinum-Cobalt color scale is described in ASTM D1209 “Standard TestMethod for Color of Clear Liquids (Platinum-Cobalt Scale)”. This ASTM method is an off-line manual laboratory method. The original test design required an observer to compare the color of a product to a known standard, and then judge the “color.” The APHA/Platinum-Cobalt color scale ranges from 0 to 500. The lowest value of 0 is referred to as water white. value of 500 is distinctly yellow.

Complete APHA/Platinum-Cobalt (Hazen) Color Analyzer System:

  • Unique dual beam optics – for long term, stable operation
  • Up to two (2) independent measurement points – for added analytical flexibility at reduced cost per point
  • High efficiency yet rugged fiber optics – analyzer electronics can be located away from a hazardous sample point
  • In-door touch screen or Ethernet (Modbus TCP) – easy local or remote analyzer operation and control
  •  Analytical calculations are all encoded in the software – answers and alarms are clearly reported
