Product - pH HQd Meters and IntelliCAL™ 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
