1. Specications

The Model PH8HF¨ ow-through type holder is used:

• To connect two pipes and provide a “ow-through” path between them.

• To mount a pH sensor; the sensor measures the pH of liquid owing through the holder.

Holder versions with or without cleaning for the pH sensor - ultrasonic cleaning or air/water jet cleaning - are available.

1.1 GeneralSpecications

1.1.1 PH8HF Flow-through Type Holder

However stainless steel is recommend in any of the following cases:

• The liquid contains organic reagent, oxidizing agents, etc., which can attack polypropylene.

• The temperature/pressure correlation of the process condition falls within the hatched area of the diagram shown right.

• The use of polypropylene is not reasonable from a viewpoint of strength or past experience.

For stainless steel, normally a 3 to 14 pH value is recommended.

CAUTION

Select the material of wetted parts with careful consideration of process characteristics. Inappropriate selection may cause leakage of process uids, which greatly a󰀨ects facilities. Considerable care must be taken particularly in the case of strongly corrosive process uid such as hydrochloric acid, sulfuric acid, hydrogen sulde, and sodium hypochlorite. If you have any questions about the wetted part construction of the product, be sure to contact Yokogawa.
