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.

Segment: Scientific

Division: Water Quality

Manufacturing Company: HORIBA Advanced Techno Co., Ltd.

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.

Quick Nutrient Analysis in Strawberry Production

New aqueous cleaning system for acrylic paint films on paper supports has been developed. Isotonic aqueous cleaning solutions that match the pH and conductivity readings of acrylic paint films and paper supports obtained from agarose gel pellets have been shown to be effective in reducing or removing dirt, dust, active mold growth and associated stains, tide line stains, and discoloration.
