Ion Selective Electrodes

Ion-selective electrodes are used for the electrochemical determination of the concentration of certain ions in solutions. Perform fast and accurate measurements with high quality Hach Lange ion selective electrodes and reagents. The range includes sensors for determining the concentration of ammonium, ammonia, sodium, nitrate, fluoride and chloride ions. In addition to electrodes, you can purchase calibration standards, ionic strength regulators, reagents and filling solutions from us. Laboratory Ion Electrodes are available in various cable lengths (1 and 3 meters) and can be purchased complete with all required calibration reagents and storage solutions. As the official representative of the Hach company, we supply a full range of electrodes and meters, if you have not found the model or the parameter you are interested in, please contact us by email, phone or use the form on the Contacts page.
