Product - pH HQd Meters and IntelliCAL™ Probes
pH Meters & Probes
Choose from Four Models, Ultra-Performance to Basic
Hach’s HQd meters work with IntelliCAL™ ultra, rugged, standard refillable and standard gel-filled pH probes to meet your measurement needs. Multiple probes work with one meter, without the need to recalibrate. Track performance with calibration history. A variety of cable lengths available ranging from 1 m for lab to 30 m for rugged field use.
Hach HQd IntelliCAL smart probes:
- automatically detect the testing parameter
- automatically recognize the calibration history & method settings
- minimizes errors
- minimizes setup time

IntelliCAL pH Probes
pH Ultra Probes
Gives fastest response compared to competitor probes. Ideal for working with difficult samples such as low-ionic strength (pure water) or rapid measurement of many sample types.
Rugged pH Probes
Designed for harsh environments. Features a super-tough, stainless steel body and polymer shroud that protects the sensor from impact. Reinforced, steel-sheathed cables are durable, yet manageable. Waterproof for 24 hours at a depth of 30 meters.
Standard Refillable pH Probes
Liquid-filled pH probe also measures temperature. Non-submersible.
Standard pH Probes
Low-maintenance gel-filled pH probe also measures temperature. Waterproof for up to 24 hours at a depth of three meters.
