Resistivity Sensors & Probes

In-line resistivity sensors for pure water applications

A resistivity sensor is an analytical instrument designed for monitoring resistivity in ultrapure water (UPW) used in microelectronics and semiconductor manufacturing. Resistivity is the reciprocal measure of conductivity, and quantifies how strongly a given material opposes the flow of electrical current. Resistivity analyzers provide a critical measurement to ensure that water used in electronics manufacturing does not carry ions that can damage the product during production.

What is resistivity?

Electrical resistivity is the reciprocal of conductivity. Resistivity is the intrinsic property that quantifies how strongly a given material opposes the flow of electric current.

What is a resistivity sensor?

A resistivity sensor is an in-line sensor that provides a continuous measurement of resistivity in a water system. This measurement is often used in electronics manufacturing to monitor and control the purity of ultrapure water (UPW). METTLER TOLEDO resistivity sensors and probes are specially designed to measure accurately in low conductivity waters. 

What transmitters are METTLER TOLEDO resistivity sensors compatible with?

Resistivity sensors can integrate with any appropriate METTLER TOLEDO water transmitter that is suitable for conductivity or resistivity.  These resistivity and conductivity transmitters include the M200, M300 Water and M800 Water transmitters. The exact transmitter for your application should be selected in consultation with your local METTLER TOLEDO representative.
