Soak the sensor in 5 - 10% Hydrochloric acid (HCl) in water solution. for 5 - 10 minutes, then rinse. If you have trouble finding 5 - 10% HCL you can buy muriatic acid at a building supply house and it is usually 20 - 30% HCL. Check the label. Dilute it with tap water to get something close to 10%.
BE VERY CAREFUL WHEN DILUTING THE ACID. USE PROTECTIVE CLOTHING (GLOVES, FACE SHIELD ETC.) ALWAYS ADD ACID TO WATER, NEVER ADD WATER TO ACID.
Conductivity sensors and electrodes are used to measure process conductivity, resistivity, WIFI, demineralizer water, RO water, percent concentration, boiler blowdown and TDS. Various installation options including retractable, flow thru, immersion, and direct insertion. Proper electrode/sensor selection is critical for optimal measurement results.
Liquid analyzers are used for monitoring process chemistry including water quality, providing process optimization and control.
Process analyzers are used to determine the chemical composition or physical properties of substances involved in industrial processes.
