Series of On-line COD Analyzers

The AppliCOD™ Series of On-line COD Analyzers are built on probably the most advanced and versatile analytical mainframe available for measuring COD values in water, bringing new levels of automation, reliability and performance.
Depending on your local water regulations, your first option is to choose the appropriate standard method:

  • Wet-chemical oxidation by potassium dichromate (K2Cr2O7)
  • Wet-chemical oxidation by potassium permanganate (KMnO4)

The second generation of the standard AppliCOD™ is equipped with a new analyzer enclosure consisting of a solid steel back, combined with an ergonomic ABS hinged part. The wet part has been revised for optimal operation and low maintenance:

  • Water-cooled reflux condenser for increased stability
  • Shorter liquid pathways: reagents, cooling, drain
  • Transparent door allows instant 180° visual inspection
  • Reduced environmental footprint (60% weight reduction)

All AppliCOD™ Series share similar high quality components, such as our long-life peristaltic pumps and precision micro pumps, and the same analytical techniques.

Compliance with international standard methods: wet-chemical oxidation conform with ISO 6060 (potassium dichromate method); or ISO 8467 / JIS K0806 (potassium permanganate method)

NEW: introduction of mercury-free method for high chloride applications

Analytical mainframe available in several configurations depending on standard method, measuring ranges and individual requirements

MW model: accelerated sample oxidation by built-in microwave unit (dichromate method only)

Second generation design with small footprint and shorter liquid pathways

Complete separation between electronics and wet part

Multiplexing up to eight (8) sampling points possible
