pH/ORP Probe - Overview - METTLER TOLEDO

pH/ORP Probe

Reliable in pure water treatment applications

METTLER TOLEDO Thornton's robust pH/ORP sensors deliver dependable measurements in water treatment processes. Smooth membrane surfaces and unique reference junction designs resist fouling in dirty samples.

pH/ORP sensors with Intelligent Sensor Management (ISM) technology carry calibration and other data in on-board memory, allowing convenient pre-calibration in a convenient location. In addition, their digital output signals are far more stable than analog signals.
