Order probes only for parameters currently required, and add additional probes in the future. The back-lit display simultaneously reads temperature in user selectable °C & °F. All measurements are automatically temperature compensated. DO measurements can be compensated for salinity, while Oxygen in Air (O2) can be compensated for altitude.
Automatic calibration recognition of pH buffers 4, 7 and 10. Also features auto power off, hold, min/max, fold-out easel back and a tripod screw. Comes with 9V battery and hard-shell, foam-lined carrying case with room for one or two probes (not included). EPA Equivalency Method: 360.1 and Alpha Method 2580.1992.
