COD Colorimeter Model: YSI 910 Range 0-150 to 15000mg/l  YSI  USA

Description: 

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:

Automatic data storage; 16 data-sets with date and time stamp

Large, backlit LCD display

IP68 waterproof case; easy to hold or set on benchtop; floats

Innovative light shield prevents moving parts or separate pieces that can easily be broken or lost

User-calibration to any government or organizational standard (for example N.I.S.T. or ISO)

Resolution can be improved for specific range requirements

Known interferences can be adjusted for the sample

Auto shutoff extends battery life
