Unpacking and Inspection

Inspect the outside of the carton for any damage. If damage is detected, contact the carrier
immediately. Inspect the hardware. Make sure all the items in the packing list are present and in
good condition. Notify the factory if any part is missing. If the sensor appears to be in satisfac-
tory condition, proceed to Section 2.2, Mounting.
NOTE: Save the original packing cartons and materials as most carriers require proof of damage
due to mishandling, etc. Also, if it is necessary to return the sensor to the factory, you must
pack the sensor in the same manner as it was received. Refer to Section 6.0 for return instruc-
tions. If the sensor is to be stored, the vinyl boot should be filled with pH buffer solution and
replaced on sensor tip until ready to use.
CAUTION
Buffer solution, in the vinyl boot, may cause skin or eye irritation.
WARNING
Glass electrode must be wetted at all times (in storage and in line) to maximize sensor life.
2.2

Mounting

The sensor has been designed to be located in industrial process environments. Temperature
and pressure limitations must not be exceeded at any time. A caution label regarding this
matter is attached to the sensor. Please do not remove the label. See Figure 2-1.
CAUTION
Internal electrolyte fill solution may cause skin or eye irritation.
Mounting Guidelines:
1. Shake the sensor in a downward motion to remove any air bubbles that may be present
inside the tip of the pH glass.
2. Do not install the sensor on the horizontal. The sensor must be 10° off the horizontal to
ensure accuracy.
3. Do not install the sensor upside down.
4. Air bubbles may become trapped in the sensor end between the glass bulb and the sensor
body. This problem is most commonly encountered in areas of low flow or during calibration.
Shake the probe while immersed in solution to remove bubbles. This problem can be
avoided by ordering the sensor with the slotted tip (option 41).
In most cases, the pH sensor can simply be installed as shipped and readings with an accuracy
of ± 0.6 pH may be obtained. To obtain greater accuracy or to verify proper operation, the
sensor must be calibrated as a loop with its compatible analyzer or transmitter.
