HK-8080 Residual Chlorine Analyzer adopts an electrochemical technology to realize real-time online monitoring of residual chlorine by measuring the relationship between the current change caused by chemical reaction on the electrode and the concentration of analyte. It can meet the online monitoring of four parameters at the same time: residual chlorine, HClO, temperature and pH. It can be used to monitor the residual chlorine online in the environment of tap water, pipe network water, water treatment disinfection and wastewater treatment.
◆ Optional pH automatic or manual compensation
◆ Unique temperature compensation method can eliminate the influence of temperature on measurement results.
◆ Realize monitoring at the same time of four parameters : residual chlorine, HClO, temperature and pH.
◆ The electrochemical method without reagent.
◆ Equipped with flow cell of manual sampling, and the manual sampling is convenient and quick.
◆ Real-time online monitoring without reagent replacement.
◆ SD card can be used to upgrade on site or retrieve data.
