HOBOware Pro is required when using the HOBO Waterproof Shuttle. See compatible items below.
The only pocket meter that directly measures conductivity in a 0.12 mL sample and converts it to salinity or salt concentration. You do not need a beaker to calibrate the meter or measure a sample. Simply place a few drops of the standard or sample on the sensor. This procedure saves you time and prevents you from wasting your valuable sample.
Minimum sample volume: 0.12 mL
Salinity and temperature display
Up to 2 calibration points
Automatic calibration
Automatic standard recognition: 0.50 and 5.00% NaCl
Automatic temperature compensation: 2%/ºC fixed
Temperature calibration: 5 to 40.0 ºC
2 salinity curves: NaCl and seawater
Automatic stable measurement/auto hold
