Model: HI93754A 25
Type: Low Range COD reagent kit using the EPA-approved dichromate method (with mercuric sulfate for chloride suppression)
Test count: 25 pre-dosed vials (approx. /3 /mL each)
Concentration Range: 0 – 150 /mg/L O
Resolution: 1 /mg/L
Accuracy: ±5 /mg/L plus ±5% of reading
Designed for wastewater, environmental, and industrial samples that may contain chloride—thanks to mercuric sulfate inclusion
Vials contain pre-measured reagents, cutting down time on prep and cleanup
Follow EPA Method 410.4: heat the sealed vial under acidic conditions → hexavalent chromium is reduced to trivalent → measure color intensity → photometer displays COD in mg/L O
Many photometers support barcode detection for method and lot tracking—ideal for GLP compliance
Contains mercuric sulfate (HgSO ):
Effective at reducing chloride interference
Means used vials are classified as hazardous mercury waste—must be disposed of accordingly
