Performing calibrations has never been easier

Most measurement problems are due to weaknesses in  procedures for calibration. With a built-in "step by step" calibration and troubleshooting guide, this instrument ensures you succeed every time.

Transfer your measurements at the touch of a button

Whether you're at the facility or working in the field, the Hach® HQ Series portable meter ensures your data is securely transferred via USB or Bluetooth*. Benefit from additional data validation when you connect the field meter to Claros Data Management software.

Sensors for most applications

We offer both standard laboratory sensors and robust Intellical smart sensors for field use. The HQ series can measure a wide range of parameters including Total Dissolved Solids (TDS), Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Temperature, Conductivity and pH. The smart sensors are automatically recognized by the HQ meter and retain calibration history and method settings to minimize errors and time consumption. They are built on proven technology to deliver market-leading accuracy and response time – even when measuring in challenging fluids or challenging operating environments.
