The Model DO-32a low density Dissolved Oxygen
meter is battery operated. It incorporates a galvanic
cell for water quality monitoring of rivers and lakes.
It is also well suited for Dissolved Oxygen management
in BOD waste water treatment tanks, or culture ponds
or other marine environments.
The unit provides pressure (water pressure) and salinity
compensation together with temperature compensation
and offers truly reliable data.
The Model DO-32a is easy to use with a simple one
touch air and automatic calibration. This field portable
unit is compact, light weight, and water resistant
Features
Wide dynamic Automatic Range Selection
Covers wide range from 0~20 micro-g/litre to 0~20
milli-g/litre measuring ranges. In addition with this
wide measuring range, full automatic range selection
function is available. The automatic temperature compensation
function enables measurement from ultra low density
levels such as micro-g/litre (ppb) range to air saturated
high ranges, with accurate performance
High response & Long Life Span
Newly developed membrane type polarographic electrode
is used in the sensor. Therefore, long life span and
high response are realized. As two versions of 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 perform zero check calibration by electric zero
(panel zero check) as well as conventional calibration
by zero standard solution.
Temperature
Measuring Function
Temperature and dissolved oxygen readings can be displayed
simultaneously and this data can be output from the
meter to an analog recorder for monitoring (recorder
available separately)
Compact Design & Easy Maintenance
The supplied flow cell is designed be compact and
provide easy maintenance and operation. The main unit
is housed in a splash-proof enclosure, thus it will
be durable against water splashing if installed in
a sampling rack.
Dual Power Sources
The instrument can be used on DC power source as well
as AC power. Consequently it can be used for field
work where AC power source is not available. 400 hours
of continuous measurement can be achieved when alkali
dry cells are loaded.
Analog Record Output Terminal
Analog recorder can be connected to the output terminal,
variation of dissolved oxygen and temperature can
be monitored and recorded continuously.
