The PEI (Polyetherimide) resin body is easy to clean and resistant to many aggressive chemicals.
The porous PTFE (Polytetrafluoroethylene) junction is equally resistant to aggressive chemicals.
The double junction design presents a silver‑free electrolyte solution interacting with the sample, making the
electrode less susceptible to clogging and guaranteeing a fast response and stable reading.
