Mix & Match with IntelliCAL smart probes!

Our HQD IntelliCAL probes are smart, robust and Easy to Use in the field.

A wide variety of IntelliCAL standard and rugged probe options make the HQd meters the most flexible instrument available in the market.
HQd digital meters offer a complete portfolio of testing parameters with standard and rugged IntelliCAL smart probe options.  Hach's HQd system gives maximum measurement flexibility and ease of operation with interchangeable probes and automatic parameter recognition.

Standard and Rugged probe options available for pH, conductivity, dissolved oxygen, ORP and ISE parameters. Simply plug the probe into the HQd meter and the parameter is automatically detected.
Calibration history and method settings are stored in the probe. Ideal for multi-user, multi-meter environments as critical information stays with the probe.

Temperature sensors integrated in all IntelliCAL probes saves time, simplifies the measurement and ensures accurate test results.

All probes are suitable for portable and benchtop models:

  • pH; gel and liquid probes
  • Dissolved Oxygen; with breakthrough LDO technology
  • Conductivity
  • Ion Selective Electrodes; sodium, fluoride, ammonium etc.
