The MD 100 COD is a dedicated, single parameter, instrument for COD Analysis. No need to purchase a multi-parameter colorimeter or spectrophotometer to get access to this critical waste water testing parameter!

The instrument utilizes Lovibond VARIO COD tube test reagents, which are available in three testing ranges. The reagents meet US EPA requirements for reporting purposes. Mercury-Free versions are also available for non-reporting purposes.

Please note, this instrument is supplied without reagents.

The MD 100 has several key features that make it a favourite among users.

Waterproof Design - The IP 68 design of this instrument ensures that the MD 100 remains water-tight for up to 1 hour at 0.1 meters. Don't worry about dropping the instrument into a body of water - it floats!
Accurate, Reproducible Results - The optical system of the MD 100 utilizes LEDs and interference filters which quickly gives you results that you can be confident in.
User Calibration Mode - A one-point calibration is possible. Additionally, all MD 100 instruments have the ability to display readings directly in ABS or %T units.
One-time-Zero Function - Don't waste time waiting for your instrument to Zero after each test. When testing a new sample, zero the instrument once and all subsequent tests of that sample do not require you to re-zero the instrument.
Automatic Data Storage with Transfer Capabilities - The MD 100 automatically stores the last 16 readings with time and date stamps. These results can be transferred to a spreadsheet using the IRiM accessory.
Ergonomic Design - Whether you're using the MD 100 out in the field or in the lab, the design of the instrument makes it easy to handle and view the display. If you're using the instrument in the lab, the rubber feet on the bottom of the housing eliminates the need for two-hand operation or to chase your instrument around the workbench.
Factory Programmed - All MD 100 instruments are supplied and ready to use with up to 14 calibration curves. All you need to do is select the test you need, prepare your sample and test!
Scroll Driven Menu System - The simple interface allows you to quickly reach the test you need. When the instrument is turned on, it will automatically display the last test used.
