HD 3409.2 Dissolved
Oxygen Saturation Index Meter Datalogger. |

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.

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 probe’s quick calibration function guarantees timely
correctness of the performed measurements.
