pH / ORP electrodes

pH and ORP are important parameters for water quality, and a wide range of technological applications depend on the ability to measure and control each. Both pH and ORP represent types of ion activity in liquids: pH measures the activity of hydrogen ions, and ORP represents the potential transfer of electrons between chemicals or chemical compounds. Our range includes Hach Lange combination, glass and refillable pH electrodes for a wide range of applications from ultrapure water and food to wastewater and viscous samples. As an official representative of Hach, we supply a complete range of pH / ORP electrodes and related products: buffers and filling solutions. If you cannot find the model you need, call us, contact us by email or use the form on the Contacts page.
