Meters and probes pH Oxygen Conductivity

Conductivity, Dissolved Oxygen, Redox Potential, pH, TDS: If you want to control these parameters, you need to use electrochemical meters to reliably and quickly characterize water quality. The devices can work in any environment, they are portable, intuitive and easy to use. The HQD laboratory multivariable meters or the HQ and HQd series portable meters are useful helpers for analyzing industrial wastewater, drinking water, swimming pool water, or water used in the food and beverage industry. Hach Intellical sensors are automatically recognized by the meter and are compatible with both measurement platforms. The sensors are available in both laboratory and field versions. The prices for the "HQ series portable meter or HQd + sensor" kits are lower than when purchasing these items separately. Filter by parameter or contact us to find a meter, sensor, solutions and standards that meet your specifications.
