Low Level Dissolved Oxygen Meter DO-32a

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. Main Unit DO-32A Low Density DO Meter for continuous thermal water systems.
