Portable oximeters

Hach's HQ and HQd series portable dissolved oxygen meters provide fast results in both fresh and salt water, with measuring ranges from 0.05 to 20 mg/L with a resolution (accuracy) of 0.01 mg/L. The operating temperature range for dissolved oxygen meters is typically 0 to 60 ° C. The portable dissolved oxygen meter can also measure other parameters: pH, biological oxygen demand, conductivity, salinity. The field versions of the dissolved oxygen sensors are equipped with a pressure sensor module and a temperature sensor. Ideal for measuring dissolved oxygen in all types of external environments such as rivers, surface and ground water, ponds, lakes, seas, waste water treatment plants, raw water, drinking water tanks to determine water quality in technological processes.
