Hanna Instruments edge® Dedicated Benchtop Conductivity/TDS/Salinity Meter

Hanna Instruments is proud to introduce the world’s most innovative Conductivity/TDS/Salinity meter. edge®’s ground-breaking design is the culmination of Hanna’s vision, design capabilities, integrated production and world-class R&D. edge® is a single meter that can measure Conductivity, TDS and Salinity and is incredibly easy to use.

  • 3.5 mm probe input
  • Wall mount cradle with built-in charger included
  • Cradle with electrode holder included
  • Two USB ports
  • Data logging of readings, GLP data, date and time
  • Two operating modes

The edge® EC/TDS/Salinity meter is supplied with the highly advanced  HI763100 four ring platinum conductivity probe that has a built-in temperature sensor for automatic temperature compensated measurements. The four ring technology allows for a wide range of measurement with a single probe as compared to amperometric two pole probes that have a limited range and can suffer from polarization effects. A built-in microchip stores the model number, serial number and calibration information including the standards used and the date and time the last calibration was performed, and is automatically retrieved by edge® once the electrode is plugged in. The HI763100 probe has a glass and PVDF body with a PEI (polyetherimide) sleeve. Both materials have excellent resistance against many aggressive chemicals.

The edge® features a capacitive touch keypad that gives a distinctive, modern look. The keypad is sensitive enough to be used with laboratory gloves and has a fast response. Since the keypad is part of the screen, there are no buttons to get clogged with sample residue.

The edge® features a 5.5” LCD display that you can clearly view from over 5 meters away. The large display and it’s wide 150° viewing angle provide one of the easiest to read LCD’s in the industry.
