1、 Instrument description:

The measuring instrument willGB11893-89The ammonium molybdate spectrophotometric method is combined with computer technology, and the principle of microcomputer photoelectron colorimetric detection is applied to replace the traditional visual colorimetric method, eliminating human errors and greatly improving measurement resolution. The automation of the measurement process has been achieved. It can be applied to the monitoring of sewage outlets of factories and mining enterprises, the monitoring of imports and exports of urban sewage treatment plants, the monitoring of water quality of Rivers and Lakes, and the process control of sewage treatment facilities.

2、 Main functional features：

• The measurement method complies with the national standardGB11893-89The regulations have a good correlation with manual analysis.

• Large screen LCD backlit display, Chinese operating interface, user-friendly programming.
