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
• 2-year warranty

If you are interested in measuring multiple parameters or chlorine only, then you may be interested in the YSI pHotoFlex colorimeters or the YSI 900 Chlorine Colorimeter.

OI Analytical validates the hardware configuration and performance of every method supplied with the FS 3700 analyzer providing users a total analysis solution. Methods for aqueous samples, soil or plant extracts are available to support environmental compliance monitoring, process optimization and research applications.

Modular hardware allows FIA and/or SFAmethods to be run interchangeably onthe same unit. Multiple FS 3700 can belinked to provide additional channels ofconcurrent analysis.

An automated injection valve is installed in theanalysis module chassis when required to runa flow injection analysis (FIA) method.

Each chemistry cartridge is pre-assembled withall components needed to perform a validatedanalysis method just attach the pump tubingand detector flow cell.Ordering by 'channel' provides a convenientway to configure the 3700. Modular, flexiblehardware provides a great platform for research, in-house or proprietary methods

In-line devices for reactions requiringheating or UV digestion are mountedon the underside of chemistry cartridges.FlowView software provides user programmablecontrol of the UV lamp and cartridge heater setpoints in 1 C increments.

Photometric and amperometric detectormodules plug-in to the FS 3700 to supportmethods employing colorimetric chemistriesor amperometric measurements. Built-in A/Dand ISE capability are standard in each chassis.The Expanded RangeTM photometric detectorand auto-scaling software virtually eliminateoff-scale samples. A single calibration curve canrange from low ppb to high ppm concentrations.
