Hach Lange's portable HQD metres and INTELLICAL electrodes measure the classic electrochemical parameters pH, conductivity and dissolved oxygen, using the drift-free optical method LDO.
What makes HQD special is the newly developed INTELLICAL sensors: They store all relevant parameters and transmit them digitally to the meter. Thus making them safe from interferences and allowing for cable lengths up to 30 m even for pH! Previously inaccessible measurement locations e.g. boreholes and bridges are now within reach. No need to draw a sample first.
The waterproof outdoor electrodes (IP67) have a hull made from stainless steel and are suitable for the toughest challenge. Their weight prevents them from drifting on the surface in strong currents. The impact protection of the sensor head can be removed for cleaning purposes.
HQD is available as a complete set with electrodes in a rugged field kit case. Additionally there is a wide range of buffer and standard solutions to choose from, plus further practical accessories.
