Pinnacle/SI Analytics pH Electrodes

The 3-in-1 electrodes measure pH, reference, and temperature in one electrode. These electrodes are constructed out of an epoxy material for increased strength and durability. The 3-in-1's temperature compensation will only work with our 300 and 400 series meters. The refillable 3-in-1 electrode has a patented ion barrier which produces the fast response of an Ag/AgCl electrode without the use of AgCl in the reference solution. This results in a tris compatible electrode. This electrode also features patented replaceable junction for extended electrode life.

Special Features: Replaceable Junctions

Slow response times and unstable readings are most often caused by clogged or contaminated reference junctions. Our patented replaceable junction lets you restore your electrode to like-new performance in minutes, at a fraction of the cost of a new electrode.
