The HQ series is for water quality professionals who want to perform electrochemical analysis for field and lab environments. Our new portable platform will allow you to collect intuitive, accurate measurements, manage data, and easily review results, while supplying an IP 67 robustness rating.

They provide a true rugged, field-ready solution with on-screen, visual step-by-step operating guidance that provides users with confidence in reporting and managing their results. Unlike other field meters with basic user interfaces and without easily accessible data, the HQ series secures, simplifies, and accelerates the complete measurement process for field users.

Performing a successful calibration has never been so simple. Most measuring issues are due to incorrect calibration procedures. With our illustrated, step-by-step on-screen calibration and troubleshooting procedures, water quality professionals can succeed every time.

Deliver your daily activity in just a few clicks. Whether you are at your facility or working in the field, the Hach HQ series portable meter ensures your data will be safely transferred via USB or optional Bluetooth.

Sensors designed for every application. We offer standard laboratory and rugged field Intellical™ smart sensors with the HQ series to measure a wide variety of parameters including Total Dissolved Solids (TDS), Optical Dissolved Oxygen (ODO), Biochemical Oxygen Demand (BOD), temperature, conductivity, and pH. Intellical™ smart probes are automatically recognised by HQ meters, retaining calibration history and method settings to minimise errors and set-up time. They incorporate proven technology to deliver superior accuracy and response times - even when measuring challenging samples or challenging operating environments.

Peace of mind: Hach service and support will be there for you. HACH Technical Support, Field Service, and Central Service Teams work together with over 80 years of electrochemistry expertise to help you maximise instrument uptime, ensure data integrity, maintain operational stability, and reduce compliance risk. Never feel alone when you need support.

Choose from theree models, including the three-input HQ4000 series, dual-input HQ2000 series, and single-input HQ1000 series. These meters offer a range in measurement versatility - eliminating the need for multiple pieces of equipment.
