Water Quality Online Automatic Monitoring Analyzer
Product Introduction
Overview
The independently developed automatic water quality online analyzer (based on the chemical analysis method according to national standard) utilizes sequential injection analysis, featuring a streamlined flow path and minimal reagent consumption. This instrument is capable of automatically executing sampling, reaction, colorimetry, calculation, and cleaning processes, enabling precise and consistent real-time monitoring of water quality indicators. Furthermore, it supports intelligent fault self-diagnosis, automatic reset under abnormal conditions, power failure recovery function. It also facilitates automatic range switching for measurements and remote control (anti-control), as well as various sampling modes such as scheduled, interval-based or remote sampling.
Application
It is suitable for the detection of industrial process water, sewage wastewater, urban and rural municipal wastewater, as well as surface water in rivers, lakes, and seas.
