Water quality professionals facing calibration challenges that compromise data accuracy now have a powerful solution. The Hach® HQ series portable multiparameter water quality meters introduce groundbreaking "what-you-see-is-what-you-get" calibration technology and advanced smart sensing capabilities, delivering unprecedented precision and convenience.

Recognizing that improper calibration procedures frequently cause measurement inaccuracies, Hach® designed the HQ series with intuitive, screen-guided calibration and troubleshooting features. Clear graphical instructions enable even first-time users to perform flawless calibrations, ensuring consistently accurate results across field and laboratory applications. The system securely transmits data to computers or storage devices for efficient management.

The HQ series' standout feature is its compatibility with Intellical™ smart electrodes, available in laboratory-grade and rugged field configurations. These sensors measure critical parameters including total dissolved solids (TDS), optical dissolved oxygen (DO), biochemical oxygen demand (BOD), temperature, conductivity, and pH. The plug-and-play electrodes automatically register with HQ meters, loading calibration histories and method settings to minimize human error and setup time. Engineered with proven technology, they deliver exceptional precision and rapid response even with challenging samples or in harsh environments.

Backed by over 80 years of electrochemical expertise, Hach® provides extensive technical support through specialized teams focused on maximizing instrument uptime, ensuring data integrity, maintaining operational stability, and reducing compliance risks.
