pH and ORP meters

This section of the catalog presents the Hach range of high-precision and easy-to-use laboratory and portable pH and ORP meters. They all have a basic set of functions and are suitable for applications where acidity needs to be measured and monitored. Compact benchtop and portable pH / ORP meters provide high quality pH / mV measurements at the push of a button. All sensors of the Intellical series are compatible with the meters. Depending on the type of electrode connected, which is automatically recognized, the meter is able to analyze the pH of aqueous solutions, food products, drinks, surfaces, viscous samples, soil. Hach pH meters measure in the range of 0 - 14. Assortment also includes pH meter + electrode kits. To select a ph meter, use the filtering function or contact us.
