2.1 UNPACKING AND INSPECTION.
Inspect the carton for any damage. If damage is detected, contact the carrier immediately. Inspect the hardware. Make sure all the items on the packing list are present and in good condition. Notify the factory if any part is missing. If the sensor is in satisfactory condition, proceed to Section 2.2, Mounting.
NOTE
Save the 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 7.0 for instructions. If storing the sensor, the vinyl boot should be filled with pH buffer solution (pH 4 buffer rec- ommended) and replaced on sensor tip until ready to use.
CAUTION
Buffer solution in the vinyl boot may cause skin or eye irritation.
NOTE
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 pertinent caution label is attached to the sen- sor. Please do not remove the label. See Figure
CAUTION
Internal electrolyte fill solution may cause skin or eye irritation.
Mounting Guidelines:
1.Shake down the sensor to remove any air bub- bles that may be present inside the tip of the pH glass.
2.Do not install the sensor horizontally. The sensor must be at a minimum of 10° off the horizontal (sensor glass bulb pointing down) to ensure accuracy.
3.Do not install the sensor upside down.
4.Air bubbles may become trapped on the sensor glass bulb. This problem is most commonly encountered in areas of low flow or during cali- bration. Shake the probe while immersed in solu- tion to remove bubbles.
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 cali- brated together with its compatible analyzer or trans- mitter.
