The PHE-7451-15 is a combination pH sensor designed specifically for
insertable use in process and waste water applications. The outer body
material is PPS and has 3/4" MNPT(or optional 1" MNPT) front
and rear facing threads. The double junction reference cell is highly
resistant to electrode poisoning solutions, while the use of the non-fouling
patented Porous PTFE liquid junction ensures a steady presence of
reference electrolyte. The PHE-7451 assures a low maintenance service
life in most applications. The concave sensor configuration (see drawing
above protects the pH bulb from particulate matter and provides a
cleansing flow without affecting critical line pressure characteristics.
Use of the high temperature version is recommended where service
temperatures continuously exceed 80°C.
† Price are shown in RMB.
Note: Comes complete with electrode care instruction sheet and 4.6 m (15 ft) of cable.
For non-standard cable lengths replace the suffix "-15" in the model number with the required length in feet, add $2 per foot to price. (Addtional per foot cost applies to the entire cable length).
For high temperature reference cell, add suffix "-HT" to model number, add $35 to price.
For HF/Fluoride resistant electrode, add suffix "-HF" to model number, add $50 to price.
