Knowledge popularization of main application fields and functional characteristics of automatic monitoring quality control instrument

The automatic monitoring quality control instrument is a health tool that can check whether the online water quality monitoring equipment is operating normally and whether the analysis data is valid. As long as the instrument consists of a control center and a quality control terminal, one control center can control multiple quality control terminals. Application field of automatic monitoring quality control instrument: quality control of water quality online monitoring instrument in water pollution source online monitoring system; quality control of water quality online monitoring instrument in surface water quality automatic monitoring system; other needs online monitoring instrument quality control. Functional characteristics of automatic monitoring quality control instrument: Quality control mode: immediate quality control, timing quality control, periodic quality control; Working mode: manual and automatic two working modes; Idle time quality control: intelligently judge the idle time of the analysis instrument; Access control function: Electronic access control, password authority login; Multiple communication methods: local control system and remote control system: wireless, wired Modularity: one display controller controls multiple quality control terminals, and each quality control terminal corresponds to an online monitoring instrument; Remote mode: through the remote control system to realize quality control result query, classification statistics, automatic detection data quality report, personnel authority management, etc.; Operation mode: internal quality control, external quality control; Distributed layout: small size, quality control terminal placed in Next to the online analysis instrument, the sample liquid transmission distance is short, and the local occupied space is less than 0.1m; Self-inspection and alarm: through self-inspection, faults can be found and alarmed (such as lack of standard samples, standard sample failure, and can realize the early warning of standard liquid shortage ), the quality control result exceeds the standard automatic alarm; Clock calibration: two modes: immediate calibration and daily automatic calibration, the calibration time can be set according to the demand; power-off data retention: power-off due to failure, quality control instrument data retention, upload remote when power-off time control platform.
