Figure 16. Inline Probe Cleaning Solution Kit
To clean the ST-772/T sensor, remove the sensor and the DO membrane cap from the water in use, wipe
it with a damp cloth to remove debris and growing organisms, and use a cotton swab dipped in water to
clean up the dirt on the membrane surface. Unscrew the membrane cap, check whether the inside of the
ST-772/T sensor flashes blue and red light; after the inspection, screw the DO membrane cap back onto the
sensor.
8.2 Storage
Avoid long term storage at temperature over 100 °F. Avoid long term storage with the sensor exposed to
ambient light as it may reduce the membrane lifetime. In an outdoor installation, properly shield the ST-
772/T sensor from direct sunlight and precipitation.
9 Troubleshooting
If the ST-772/T sensor output signal is not stable and fluctuates significantly, make an additional ground
connection – connect the black (shield, earth ground) wire to a conductor that contacts the sample water
electrically such as a metal pipe adjacent to the ST-772/T tee.
