HD3409.2 Concentration (in mg/l) of dissolved Oxygen in liquids, the saturation index (in %) and the temperature meter.
The HD3409.2 measures the concentration (in mg/l) of dissolved Oxygen in liquids, the saturation index (in %) and the temperature using SICRAM combined probes of polarographic type with two or three electrodes and integrated temperature sensor.
Temperature is measured by Pt100-SICRAM or direct 4 wire-immersion, penetration or contact probes.

HD3409.2 dissolved oxygen meter

Model  Description 
HD 3409.2  Dissolved Oxygen concentration meter.

Thanks to an internal pressure sensor, the instruments automatically compensate for barometric pressure.
The instrument anticipates automatic compensation of the Oxygen probe membrane permeability and of the salinity of the liquid being examined. The dissolved Oxygen probes quick calibration function guarantees timely correctness of the performed measurements.
