Online residual chlorine electrode consists of a cathode and an anode, the cathode is a gold electrode, and the anode is a silver/silver chloride electrode, the cathode and anode are immersed in an electrolyte chamber filled with electrolyte, through film and measurement environment isolation, and the film can prevent electrolyte leakage or contaminant infiltration, but hypochlorous acid can pass through the film, the measured hypochlorous acid concentration and the measured current proportional relationship, through pH compensation, to obtain the residual chlorine concentration.

During the COVID-19 outbreak in China, as an expert in the water testing area,Lohand supplies thousands of residual chlorine analyzers to customers, especially for medical institutions.  
Currently, since the outbreak is under control in China, Lohand has the capacity to meet all the demands on residual chlorine analyzers in this period of time. Lohand hopes to work together with the international community in dealing with the challenge of the novel pneumonia pandemic.
As enveloped viruses are surrounded by a lipid host cell membrane, which is not robust, the COVID-19 virus is likely to be more sensitive to chlorine and other oxidant disinfection processes than many other viruses, such as coxsackieviruses, which have a protein coat. For effective centralized disinfection, there should be a residual concentration of free chlorine of ≥0.5 mg/L after at least 30 minutes of contact time at pH<8.0. A chlorine residual should be maintained throughout the distribution system.

Measuring range 0-20mg/L
Lower limit 0.05mg/L
Ph range 4-8
Accuracy ±10%(DPD)
Repeatability 0.05mg/L or 5% larger as the standard
Respinse time T90<120S
Velocity of flow ≥20L/H
