Pocket Water Quality Meters
Your lab-in-a-pocket
HORIBA's unique compact meter integrates the electrode, display and sample container to enable simple, effective on-site testing by direct measurement from a single drop.
The only pocket meter that directly measures conductivity and total dissolved solids (TDS) in 0.12ml sample. No need for a beaker to calibrate your meter or measure a sample. Just place few drops of the standard or sample onto the sensor. This procedure saves you time and prevents wasting your precious sample.
