Interchangeable plug and play probes let this versatile meter read pH, mV, ORP, conductivity, salinity, TDS, DO and temperature.

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.

Meter Dimensions: 7" × 2¾ × 2" (177 × 68 × 45 mm)
