The COD-LAB and COD-FIX are online analyzers for monitoring Chemical Oxygen Demand. The measurement range can be chosen from 0.5 to 5,000 ppm. The COD-LAB is applicable for setting up in a room or container. The COD-FIX is ideal for external installations, directly at the measurement point. The COD value is the amount of oxygen which is required for the oxidation of oxidyzable matters. The COD is measured by the consumption of an oxidation matter. Therefore Hydrogen Peroxyd (H2O2) is added to the sample.
BOD analyzer The analyzers ZAW-LAB and ZAW-FIX are semi-continuous analyzers for online-determination of the so called respirometry. Respirometry means a decrease of the oxygen content in a water sample, caused by breathing of microbiology. ZAW-LAB is applicable for installation in heated and dry rooms. ZAW-FIX can be installed outdoor. In ZAW-LAB and ZAW-FIX the sample is sucked in by means of an internal vacuum pump. A vessel where a oxygen probe is installed in is filled by the non pre-treated sample รายละเอียด
