The Intellical PHC101 series pH probes are digital, combination electrodes that measure the pH 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.

IntelliCAL PHC101 provides fast, stable response in wastewater applications - Unique solid gel probe and open reference junction specifically designed for pH measurement in wastewater.

IntelliCAL digital probes provide ultimate traceability in measurement history - Stored time and date stamp for each measurement, operator and sample ID, calibration history, parameter, and probe serial number

IntelliCAL digital probes alert the user when re-calibration is needed - No guesswork needed to provide the most reliable and accurate results with each measurement.

IntelliCAL digital probes can be moved between meters without the need to re-calibrate or re-enter measurement settings – Ideal for a multi-user environment with multiple HQD series Laboratory and Portable meters.
