Demanding applications can leach the electrolyte from the pH sensor causing measurement inconsistency and eventual failure. Hamilton refillable pH sensors solve this problem by allowing the user to replenish the electrolyte.

pH Sensor Chemotrode

Chemotrode

The ChemoTrode targets aggressive media found in industrial applications.

ChemoTrode ORP

Pressurization up to 6 bar solves issues with strong oxidizers or reducers that shorten the life of standard ORP sensors.
Ionotrode refillable pH sensor

IonoTrode

Low conductivity, pure water applications such as found in power plants, UPW, and WFI water applications.
Fermotrode pH sensor

FermoTrode

When maintenance of existing products has become exceedingly difficult, the FermoTrode fits into existing housing with no pressurization.
