	  | Description:Waterproof dissolved oxygen
 meter with polarographic probe for rough field use in any kind of weather
including rain, snow and dusty conditions.  Calibration is very simple and
straight forward using a zero solution followed by a one point air
 calibration. Meter comes with temperature compensation between 0 and 32 oC
 and has a low battery indicator to prevent user from getting erroneous
readings. | 
    	  | Applications:Rough field
use where outdoor conditions would rapidly deteriorate a nonwaterproof
dissolved oxygen probe.  Water quality can be measured in streams, lakes,
fish ponds, etc. |
