Hach® HQD Laboratory Meters
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.
A wide variety of Intellical laboratory electrodes are available to meet the most demanding laboratory applications. Intellical Red Rod pH electrodes offer exceptional performance and response time across a wide variety of sample types. The LBOD probe utilises optical technology to provide fast, accurate Dissolved Oxygen measurements while dramatically reducing maintenance costs. Additional probes for Conductivity, Total Dissolved Solids (TDS), Ammonia, Ammonium, Fluoride, Nitrate, Sodium, and RedOx (ORP) measurements complete the Intellical portfolio.
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.
