WARNING
Internal electrolyte fill solution may cause skin or eye irritation.
Wear personal protection equipment (PPE).
Avoid contact with skin and eyes.
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
degrees 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. To avoid this
problem, order the sensor with the slotted tip (option -41).
In most cases, you can simply install the pH sensor as shipped and obtain
readings with an accuracy of ±0.6 pH. To obtain greater accuracy or to verify
proper operation, calibrate the sensor as a loop with its compatible
transmitter.
1.2.1 Flow through and insertion mounting
Rosemount 396P and 396PVP Sensors have a 1-in. (25.4 mm) male national
pipe thread (MNPT) process connection at the front of the sensor for
mounting into a 1½-in. (38.1 mm) tee or the process pipes.
See Figure 1-2
Note
Do not use large pipe wrenches to tighten the sensor into a flange or other
type of mounting.
