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.
