INTRODUCTION
The HD34… family is composed of four desktop instruments for electrochemical measurements:
pH , conductivity , dissolved Oxygen and temperature .
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 , with two or
three electrodes, and galvanic type with integrated temperature sensor. Temperature only is meas-
ured 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 per-
meability and of the salinity of the liquid being examined.
The dissolved Oxygen probe's quick calibration function guarantees timely correctness of the per-
formed measurements.
The displayed data can be stored
(datalogger) and can be transferred to PC or serial printer thanks
to the multi-standard serial ports RS232C and USB2.0 and software DeltaLog9 (Vers.2.0 or later).
The storing and printing parameters can be set from menu.
Display, printing and logging always show temperature in °C or °F, and one of the parameters of
oxygen measure (mg/l O
2
, %O
2
, mbar).
Other common functions of this instrument series include: Max, Min and Avg function, the Auto-
HOLD function, the automatic turning off which can also be disabled.
The instruments have IP66 protection degree.
