The 910 colorimeter is a rugged, waterproof, single parameter instrument for the measurement of COD (chemical oxygen demand).
The EPA-approved COD test is useful for performing rapid, frequent monitoring of treatment plant efficiency, and results allow quick response to changing conditions in the waste stream while the traditional BOD5 test takes 5-days to determine results.
The instrument features a large, backlit display, a real time clock, automatic data logging as well as the ability to export data to a PC or printer using the 900 Series Data Hub for infrared data transfer.
Features for the 910 to quickly and accurately measure COD include:
YSI offers a COD empty vial disposal program as well through Safety-Kleen. Click on the "Resources" tab and look under "Tips, FAQs & Guides" to learn more or simply fill out the form on Safety-Kleen's website.
