Talk about the principle and performance of the online residual chlorine monitor

1. The residual chlorine online detector is a highly intelligent online monitor, which consists of two parts: a sensor and a secondary meter. It can measure residual chlorine, pH value and temperature at the same time. It can be widely used in the continuous monitoring of residual chlorine and pH value of various water quality in electric power, waterworks, hospital and other industries. 2. Performance support: Chinese display, Chinese menu, Chinese memorandum: simple operation, Chinese prompts throughout the operation steps. Multi-parameter display on the same screen: display residual chlorine, temperature, pH value, output current (HOCL or residual chlorine electrode input current), status and time on the same screen. History curve: Automatically store the residual chlorine measurement data every 5 minutes, and can continuously store the residual chlorine value for one month. Provides two functions of 'historical curve' display and 'timing and fixed point' query on the same screen. Notepad function: Notepad faithfully records the operation and use of the instrument and the time of alarm occurrence, which is convenient for management. Monitoring electrode function: the method, time and result of each calibration are recorded, which is convenient for query and analysis of electrode change rules. Digital clock function: Provides a time reference for various functions. The instrument is stable and does not crash: the watchdog program ensures that the instrument will not crash when it works continuously. Manual current source function: the output current value can be checked and set arbitrarily, which is convenient for detecting the recorder and the lower computer. Software setting current output mode: software selection is 0 ~ 10mA or 4 ~ 20mA output.
