The TOA DO-32a low
density Dissolved Oxygen meter is designed for very low level measurement
of dissolve oxygen down to the part per billion level (ug/L). Generally,
trace oxygen level monitoring is required in steam and cooling waters
for power generation stations, metal corrosion test facilities, atomic
power generation stations, production facilities for semi-conductor manufacturing,
and other related industries.
The DO-32 can be used
for field monitoring or real time control of water quality using its superior
electrode system and flow thru cell assembly.
The unit is battery
operated and incorporates a membrane based polarographic 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
with temperature compensation and offers truly reliable data.The 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.
