portable pH meters

The HQ Series is for water quality professionals who want to perform electrochemical analysis for field and lab environments.
The new portable platform will allow you to collect intuitive, accurate measurements, manage data, and easily review results, while supplying an IP67 robustness rating. The meters 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. Successful calibration has never been so simple.
Most measuring issues are due to incorrect calibration procedures. With the illustrated, step-by-step on-screen calibration and troubleshooting procedures, water quality professionals can succeed every time.
Unlike other fi eld meters with basic user interfaces and without easily accessible data, the HQ Series secures, simplifies, and accelerates the complete measurement process for field users.
The bundles includes the portable digital meter, the corresponding sensors including cable (1 m), a field case, a stand, a protective cover and the consumables suitable for the respective measurement.
