Versatility meets functionality with multiparameter meters

Measure pH, ion concentration, conductivity, dissolved oxygen, and temperature with a single, powerful meter. Our benchtop and portable multiparameter meters are designed to increase your productivity in the lab and in the field. Choosing a multiparameter meter reduces the amount of equipment on your benchtop or in your hands while in the field, eliminates the need for multiple meters as the display showcases multiple parameters on one unit, and saves time in transferring electrodes from meter to meter for measurements. Combine your parameters today for simultaneous measurements saving space, time, and money. Browse our complete portfolio or let one of our experts help you make a selection.
