  • Fast, accurate results
  • Safe, green chemistry
  • Strong correlation to BOD5。
  • One technology, multiple configuration

The core technology is the PeCOD® sensor, which consists of a UV- activated nano particulate TiO2 (titanium dioxide) photocatalyst coupled to an external circuit.


PeCOD conforms to Method E3515, released in 2014 by the Ontario Ministry of Environment and Climate Change (MOECC) to replace the dichromate method for COD testing.


PeCOD Measurement Method validated by ASTM International Standards Organization as ASTM D8084-17
