FU20 & PH20 PH/REDOX all-in-one Sensor

The PH20 and FU20 all-in-one sensors show how Yokogawa applies the motto “Simple is best” to sensor technology. These sensors feature four separate elements (pH, reference, temperature, ORP) in a rugged Ryton (FU20) or PVDF (PH20) body.

The integral, number-coded cable and integral NPT threads makes installation convenient. The Quick Release Adapters for the FU20 allow easy removal of the sensor for cleaning and calibration. When used with PH402, PH150, or PH202 pH converters, simultaneous measurement of pH and ORP is possible with one sensor.
