pH/ATC Polymer Combination Triode


General purpose gel filled pH electrode with built-in ATC.

SKU: E8400 Category:

A rugged general purpose gel filled pH electrode with built-in ATC/ Temperature probe. This Triode is compatible for use with EDT directION pH meters including the QP Series instruments.

This electrode is ideal for use by non-skilled operators or where physical demands are high. It does not require the use of a separate reference electrode.

Non-refillable and maintenance free.

With a 12mm inert and rugged body with a Fixed Protective Skirt, the E8400 pH combination electrode can be used in applications where an electrode arm and holder are not practical. The electrode is particularly suited for use with portable pH meters where the sample is measured whilst hand holding the electrode.

The E8400 pH Electrode with ATC comes complete with a 1 metre fixed cable and BNC and 3.5mm mini Jack Connectors. This makes it compatible with the QP451 Portable pH Meter.

Calibration is normally performed using two pH buffer solutions. A separate Reference electrode or Temperature probe is not required.

EDT DirectION offer a full range of solutions and accessories. The Buffer Solutions are available in 500ml quantities as well being available in capsules. These are to be added to de-ionised water.
