Mark as favourite

Range: 0 - 500 mg Pt/l (ASTM D1209)
Range: 0 - 100 mg Pt/l (ASTM D1209)
Path Length: 50mm (PFX/PFXi-195 Series), 100mm (PFX/PFXi-880,950,995 Series)

Often referred to as Pt-Co, Platinum-Cobalt, Hazen or APHA Colour. All terms are interchangeable and equally valid.

Used to measure clear to dark amber liquids.

Originally defined by specified dilutions of a platinum-cobalt stock solution, ranging from 0 at the light end of the scale to 500 at the darkest.

The Scale is available in a digital format on our automatic PFX and PFXi ranges of instruments, with a resolution of 1 unit.

Used extensively in the water industry but also for clear oils, chemicals and petrochemicals such as glycerine, plasticisers, solvents, carbon tetrachloride and petroleum spirits.

Choice of Visual AF Kit is very much determined by the resolution required:

  • AF329, 0 - 250 mg Pt/l, discs (CAA, 0 - 30 mg Pt/l; CAB, 30 - 70 mg Pt/l; NSB, 70 - 250 mg Pt/l
  • AF325, 10 - 250 mg Pt/l, discs (NSH, 10 - 90 mg Pt/l; NSB, 70 - 250 mg Pt/l)
  • AF328, Low Range, 0 - 70 mg Pt/l, discs (CAA, 0 - 30 mg Pt/l; CAB, 30 - 70 mg Pt/l)
  • AF327, Low Range, 0 - 70 mg Pt/l, discs (1209/1, 0 - 30 mg Pt/l; 1209/2, 30 - 70 mg Pt/l)
