Residual chlorine is the amount of chlorine that stays in the water after a certain time. The chlorine left in the wastewater can help keep it disinfected even after the initial treatment, and we can measure it to see how effective the treatment is. Testing for residual chlorine is one of the most common tests used by water treatment plants. The OPM Residual Chlorine sensor helps measure the amount of chlorine left in the water or effluent. The sensor sends signals digitally, and our smart controller shows the readings in real time.
