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
