* Handy DO Meter TOX-90 uses a polarographic sensor which is quick
in response time and excellent in stability; high-precision
measurement made easy. Unlike a galvanickel sensor, this sensor is
highly stable and minimizes deteriorated sensitivity due to
battery electrolyte or measuring electrode contamination.
* Throw-in type sensor with protective cover for field use is a
standard feature; convenient for use in rivers, lakes, and ocean.
* Chip-type replacement method makes it easy to replace membranes
and battery electrolyte.
* Seawater salinity correction function is equipped to it.
