Lovibond MD100 Photometer COD with TT
The MD 100 COD Photometer provides photometric detection to measure the COD concentration from 0 to 15000 mg/l O2. A simple button layout, robust waterproof design and large backlit display make the MD100 easy to use and ideal for testing in the field, laboratory or plant room.
The unit supplies accurate, reproduceable results using high quality interference filters with long-life LEDs as a light source. Tests are conducted using the standard small scale sealed tube method. Lovibond® Vario COD vials are available for measurements of 0-150, 0-1500 or 0-15000 mg/l. The COD photometer is programmed to measure all three ranges.
Results are automatically stored with time and date for later review, and can also be downloaded to a PC using an additional Infra Red interface.
The photometer is available as a standalone unit or as a COD measurement system including the RD125 COD reactor, one pack of COD Vario vials LR 0-150 mg/l, one pack of COD Vario vials MR 0-1500 mg/l, instructions and accessories.
