Measures dissolved oxygen to determine water quality in
environmental testing, labs, industrial and municipal waste water, aquariums
and fish hatcheries. The back-lit display simultaneously displays dissolved
oxygen (in % or mg/L) and temperature readings (in °C or °F). Automatic
temperature compensation as well as manual compensation for salinity and
altitude (all factors affecting DO readings). Features simple one-button
calibration to air. DO probe heads include built in membranes and screw on and
off for easy replacement. Also functions as a pH, ORP, Conductivity, TDS or
Salinity meter when used with the optional probes. Comes in a hard-carrying
case complete with DO probe, 2 spare probe heads, electrolyte, instructions and
a 9V battery. EPA Equivalency Method: 360.1.
