Designed for water quality experts, the advanced Hach HQD laboratory meters take the guesswork out of measurements. All HQD meters feature an advanced yet simple user interface that does not require manuals or training to operate. HQD meters connect with smart Intellical electrodes and automatically recognize the testing parameter, calibration history, and method settings to minimize errors and setup time.

Choose from 3 models, including the dual-input HQ440D and single-input HQ430D versions. These multi-parameter meters offer the ultimate in versatility and redundancy - perfect for budget-constrained laboratories.

Interchangeable Intellical probes for measuring pH, Dissolved Oxygen (DO), Conductivity, Total Dissolved Solids (TDS), Ammonia, Ammonium, Fluoride, Nitrate, Sodium, LBOD, and RedOx (ORP).

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 IP67 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.

Choose from 4 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.

Pocket Pro and Pocket Pro+ Testers measure electrochemical parameters in a broad range of water applications. The family of 12 pocket meters offers convenient portable solutions for pH, ORP, conductivity, TDS, salinity, and temperature, delivering accurate results you can be confident in. The Hach Pocket Pro+ Testers take the value a step further with replaceable sensors, powerful backlight, and multi-parameter tester options. The Hach Pocket Testers are engineered to deliver accurate results, backed up with built in performance diagnostics, you never have to guess when to clean or calibrate the sensor. Each tester is equipped with replaceable batteries for convenient field use, and a large, easy-to-read LCD screen.

The Pocket Pro and Pocket Pro+ Testers are ideal for pool water testing measuring pH, ORP, Conductivity, TDS & Temperature. The handy pocket meters are also perfect in field use for testing industrial wastewater, drinking water, and food & beverage products.

sensION+ Field Kits work as complete mobile measurement stations with ergonomic, lightweight design and IP67 protection. Screw-on calibration tubes simplify on-site calibration and minimize consumption of standard solutions. It is designed as complete field solutions – from single parameter pH meters up to multi-parameter systems for simultaneous measurement. The Sension+ offers a cost-effective complete package option to begin testing quickly pH, ORP, Conductivity, Total Dissolved Solids (TDS) and Dissolved Oxygen (DO), as well as a bundle of Ions by ISE such as Sodium, Calcium, Fluoride, Nitrate and Ammonium.
