Versatility meets functionality

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.

Whether working in food and beverage, pharmaceuticals, energy and power, education, government, or water and wastewater management, Thermo Scientific Orion multiparameter electrochemistry meters help you meet regulatory standards, ensure quantity control protocols are met, achieve your safety goals, and accelerate your path from challenge to solution.

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.
