Section 1 Product overview

The Intellical MTC101 series ORP probes are digital, combination electrodes that measure the

oxidation reduction potential (ORP/Redox) of wastewater, drinking water and general water samples.

The probes have a non-refillable, gel-filled electrolyte and a built-in temperature sensor. The open

reference junction gives an optimum electrical connection between the sample and the electrolyte

and does not become clogged. The standard probes are for laboratory use. The rugged probes are

for field use. Refer to Figure 1.

Note: Do not use the probe for measurements in organic solvents.
