Hamilton InchTrode pH Electrode

The Hamilton InchTrode is a pH electrode for demanding applications in paper making, the chemical industry and wastewater treatment. It has a robust PEEK shaft and an integrated NPT process thread, so it can be installed without an additional housing, directly in pipelines or pilot plants. As one of Hamilton’s distributors in Turkey, Mikron Proses (Üsküdar, Istanbul) supplies InchTrode electrodes and provides application consulting on sensor selection.

Single Pore junction and Polisolve electrolyte

The Single Pore liquid junction gives direct contact between the sample and the Polisolve polymer electrolyte. Hamilton lists this as a clog-free design with a very long-lasting reference system, which suits fibrous and particle-laden media. The flat membrane (HF glass) is the choice for abrasive flows, while the cylindrical membrane (PHI glass) suits applications where periodic CIP cleaning is necessary.

InchTrode model options

Model	Process connection	Membrane	Temperature and pressure
InchTrode N75F	3/4-inch NPT	Flat membrane (HF glass)	-10 to 130 °C / 10 bar g (25 °C)
InchTrode N75P	3/4-inch NPT	Cylindrical membrane (PHI glass)	0 to 130 °C / 10 bar g (25 °C)
InchTrode N100F	1-inch NPT	Flat membrane (HF glass)	-10 to 130 °C / 10 bar g (25 °C)

Versions with a fixed cable (N75FC10 and N75PC10) use a Pt100 temperature sensor; the VP6 versions use Pt1000.
