pH electrode InLab Reach Pro-425 - Overview - METTLER TOLEDO

pH electrode InLab Reach Pro-425

Origin of Precision. A glass-body, combination pH electrode with integrated temperature probe, MultiPinTM head and 425 mm long shaft for general application.

Extended application range

The extra-long shaft allows measurements in deep vessels, barrels or pilot reactors.

Always the right temperature

The integrated temperature probe guarantees you always measure with the right temperature compensation.

ARGENTHALTM - For a long electrode life

The ARGENTHALTM reference system uses silver-ion-free electrolyte. Thereby is no danger of the junction becoming blocked by sulfides or proteins.
