TheModel DO-32a low density Dissolved Oxygen meter is battery operated. Itincorporates a galvanic cell for water quality monitoring of rivers andlakes. It is also well suited for Dissolved Oxygen management in BOD wastewater treatment tanks, culture ponds or other marine environments.

The unit provides pressureand salinity compensation together with temperature compensation and offerstruly reliable data.

The Model DO-32a is easy touse with a simple one touch air and automatic calibration. This fieldportable unit is compact, light weight, and weatherproof.


Wide dynamic AutomaticRange Selection
Covers wide range from 0~20 micro-g/litre to 0~20 milli-g/litre measuringranges. In addition with this wide measuring range, full automatic rangeselection function is available. The automatic temperature compensationfunction enables measurement from ultra low density levels such as micro-g/litre(ppb) range to air saturated high ranges, with accurate performance.

Fast Response & LongLife Sensor
Newly developed membrane type polarographic electrode is used in the sensor.Therefore, long life span and fast response are realized. As two versionsof electrode are available; normal type and atomic power station use type.The Model DO-32A can meet a wide variation of application requirements.

Easy Calibration
Span calibration can be done by air and it is also possible to performzero check calibration by electric zero (panel zero check) as well asconventional calibration by zero standard solution.

Sample colour does notaffect measurement
The detector only responds to salinity (Cl-) and is unaffected by colouringadditives or seasonings.

Temperature MeasurementFunction
Temperature and dissolved oxygen readings can be displayed simultaneouslyand this data can be output from the meter to an analog recorder for monitoring(recorder available separately).

Compact Design & EasyMaintenance
The supplied flow cell is designed be compact and provide easy maintenanceand operation. The main unit is housed in a splash-proof enclosure, thusit will be durable against water splashing if installed in a samplingrack.

Dual Power Sources
The instrument can be used on DC power source as well as AC power. Consequentlyit can be used for field work where AC power source is not available.400 hours of continuous measurement can be achieved when alkali dry cellsare loaded.

Analog Record Output Terminal
Analog recorder can be connected to the output terminal, variation ofdissolved oxygen and temperature can be monitored and recorded continuously.
