COD TESTING with the 975MP Analyst
and Series 942 Mini-Analyst |
The Analyst Model 975MP,
Tube Adapter Model 975-TA,
COD Reactor
|
Orbeco-Hellige's
micro-COD Method, when performed with The Analyst, offers low-cost, simple Chemical Oxygen Demand testing fully compatible with USEPA 410.4 and Standard Methods 5220.
|
Uses convenient 16mm diameter screw-cap tubes containing a specific oxidizing agent. The tubes, containing reagents and samples, are heated at 150°C for 2-hours (or less under certain conditions) and then are inserted into the 975 TA adapter in The Analyst
for a direct test reading. The 2 hour time period is mandatory for EPA approved methods, but COD readings for non-reporting purposes may be obtained in as little as 15 minutes for readily oxidized wastes.

 COD REACTORS
COD Reactors Hold up to 15 or 30 reagent tubes (16mm) for digestion at 150°C. Compact and solidly built, the units are factory set to the correct temperature. Units include a chemical-resistant safety shield and a thermometer.
COD TUBES
 Standard tubes meet the official requirements of USEPA. They contain enough mercury to compensate for chloride concentrations as high as 2000 mg/L. Mercury-free tubes, although not USEPA approved, avoid the trouble of disposal. Each package contains 50 screw-cap 16mm diameter tubes with reagent.

| COD TESTING with Series 942 Mini-Analyst |
Model 942-061 Mid Range COD Tester |
The Orbeco-Hellige Mini-Analyst micro-COD Method offers low cost, simple COD testing fully compatible with USEPA 410.4 and Standard Methods 5220, over 3 ranges.
Uses convenient 16mm diameter screw-cap tubes containing a specific oxidizing agent. The tubes, containing reagents and samples, are heated with a convenient COD reactor at 150°C for 2 hours (or less under certain conditions) and then are inserted into the Mini Analyst's tube well. In a few seconds, the test result is displayed in terms of mg/L COD. For performing low, medium and high range COD testing, Orbeco-Hellige COD Mini Analysts are the easiest instruments to use!
