Insertion/Submersion Combination Electrodes
The PHE-7151 series combination electrodes are ruggedly constructed; the outer body is ABS with 3/4" MNPT threads at both ends. The maximum insertion length is 31.75 mm/1.25". Electrodes are annular PTFE liquid junction refillable and include 15 ft of cable with a BNC connector. For applications with temperatures up to 120°C (248°F), units are available in polyphenylene sulfide (PPS).***

These electrodes have a special plunger design allowing them to be mounted at any angle.
