Specification
The Model FU20 offers a simple and cost effective solution for a wide variety of waste water and
process applications. This all-in-one sensor provides simultaneous measurement of pH, ORP
and temperature. The rugged Ryton body is designed for easy installation into on-line via the 3/4
inch tapered threaded connections provided on both ends of the sensor.

NOTE
Cautions for using the FU20 sensor
Note that the FU20 sensor has limited life which depending on installation process.
Be careful not to allow liquid junction and glass of the pH sensor to dry out.
When storing the sensor, be sure to attach the protective cap (supplied with it on shipment) to its tip.
The sensing glass membrane of the pH sensor gradually deteriorates during storage.
A virgin pH sensor may become unusable because of its deterioration. Avoid storing the sensor
for a long time (Use within a year is recommended).
