GAOTek conductivity meters report the conductivity of a substance as an inverse function of resistivity. Resistivity is measured in ohms/cm, while conductivity is measured in mhos/cm. Our portable conductivity meters and testers are ideal for water conditioning, medical, beverage, laboratory, and other industrial applications. Our high-performance conductivity meters are reliable, high quality, accurate and affordable equipment that facilitate easy inspection and testing. They are compact, portable instruments that allow a user to conveniently work in complex conditions in a lab or onsite.
