the sky and then twist tying, zip tying, or rubber banding the bulkhead to the
cable. Making a simple curve to the cable without bending or breaking the cable
will allow you to lower the sensor into the aeration tank while the sensor points
skyward so the bubbles are no longer bursting on the membrane surface.

the conductivity sensor will provide quick readings as long as the entire sensor
is submerged and no air bubbles are trapped in the sensor area. Immerse the
probe into the sample so the sensors are completely submerged and then shake
the probe to release any air bubbles. occasional cleaning of the sensor may be
necessary to maintain accuracy and increase the responsiveness. to clean the
sensor, use the conductivity cleaning brush with a mild detergent.

pH and oRP readings are typically quick and accurate. However, it may take the
sensors a little longer to stabilize if they become coated or fouled. to improve
the response time of a sensor, follow the cleaning steps in the Maintenance
section of this manual.

these sensors may take a little longer to stabilize if the tips are dirty or fouled. If
installed with a pH sensor, always maintain a clean pH sensor for a more rapid
sensor stabilization.
these sensors can only be used in freshwater.
