The IntelliCAL PHC101 is a digital combination pH electrode with a built-in temperature sensor, designed for low-maintenance operation in wastewater, drinking water, and general aqueous testing. It pairs with HQD and HQ Series meters and is fully interchangeable between them.

• Non-refillable, gel-filled single open reference junction — no reagents to maintain
• Shockproof epoxy body protects down to the glass sensing bulb
• Digital output stores calibration history, serial number, and measurement data directly on the probe
• Automatically recognized when moved between HACH HQD or HQ Series meters, with no re-calibration needed
• Alerts the user when re-calibration is due
• Not suitable for organic solvents or samples below pH 2
