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.
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 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
