The Thermo Orion Chlorine Electrode allows total residual chlorine to be measured quickly and accurately. All forms of total residual chlorine are measured: free chlorine, hypochlorites, and chlorine bound to nitrogenous compounds. This electrode method is EPA approved for drinking water and wastewater (EPA No. 330.5).

The method permits rapid analyses to be done at the sampling site, eliminating erroneous low readings due to Cl2 loss.

(Samples not measured immediately are subject to chlorine loss due to reaction with oxidizable species in the sample).
Notable Specifications:
  • Construction: Solid state combination
  • Measurement Range: 3 x 10(-4) to 10(-7) M / 20 to 0.01 ppm
  • Temp Range: 0 to 50 C
  • Required Reference Electrode: Included
  • Reference Filling Solution: None Required
  • Calibration Standards: 100 ppm as Cl2 (977007)

If you remember the movie “Erin Brockovich,†you are already familiar with hexavalent chromium, a toxic substance that was contaminating the drinking water of people in California in the movie ( and in real life ). Although on the silver screen there was a very satisfying Hollywood resolution to the problem, there has not yet been such a happy ending in real life. The dumping of the hexavalent chromium by PG&E that the film documented took place in the 1950s and 1960s, although the company didn't tell anyone about the problem until the late 1980s. Based on current litigation around the Illinois and Indiana shores of Lake Michigan, startlingly little has changed.

BOB and MARI Will Monitor Water Chemistry in the San Francisco Bay

Scientists have had nagging questions about how ocean acidification might be affecting the waters of the San Francisco Bay. But if you can't trust BOB and MARI with your research questions, who can you trust? That's BOB, the Bay Ocean Buoy and MARI, BOB's companion mooring for Marine Acidification Research Inquiry, of course. BOB and MARI are a bright yellow, five-foot tall buoy and its companion mooring, respectively. They are anchored near the Estuary and Ocean Science (EOS) Center of San Francisco State University (SFSU). SFSU researchers are collaborating with scientists from the University of California, Davis and other funders and partner organizations on the first long-term project to monitor carbon dioxide and ocean acidity in the San Francisco Bay.
