The Chemical Oxygen Demand (COD) test is widely used as a measure of organic contamination by determining the quantity of oxygen required for oxidation of reduced species including organic matter, in a water sample using a specific oxidizing agent,

The most accurate inexpensive outfit for testing pH of any soil, sand, clay or peat. Performs 200 tests.

Powder Pack Reagents are pre-measured, unit dose reagents that have been formulated for use in Orbeco-HelliCytiva Aqua Comparator Test Kits, the SC450 Single Parameter Colorimeter Series, MC500 Multi-Parameter Colorimeter, and the SP600
