The WXZJ-CL20A Residual Chlorine Analyzer is a microprocessor-based online water quality monitoring instrument. It is used for continuous monitoring and control of residual chlorine content in drinking water treatment plants, drinking water distribution networks, swimming pools, industrial wastewater, and cooling circulating water.
The instrument features an LCD display; intelligent Chinese menu operation; selectable current output modes, freely adjustable measurement ranges, high/low limit alarm prompts, two sets of relay control switches with adjustable hysteresis range; automatic or manual temperature compensation; automatic or manual pH compensation; multiple automatic electrode calibration methods; RS485/RS232 communication for computer connection.
Depending on user needs, residual chlorine electrodes for various installation processes such as [flow-through], [immersion type], and [pipeline type] can be provided.
The complete measurement system mainly consists of two parts: the instrument (secondary meter) and the residual chlorine electrode (primary sensor). The residual chlorine electrode contacts the measured water solution, and the instrument displays the residual chlorine value, pH value, temperature value, and operating status of the water solution. |
