Product information "HI 2003-02 edge - Conductivity / TDS / Salinity Meter"


 Hanna Instruments is proud to introduce the world’s most innovative Conductivity/TDS/Salinity meter, edge®.

edge® is thin and lightweight, measuring just 0.5” thick and weighing just 8.8 ounces. edge® has an incredibly wide viewing angle, 5.5” LCD and a sensitive capacitive touch keypad.

edge® measures conductivity through its unique digital electrode. This digital electrode is automatically recognized by the meter, providing calibration data and a serial number when connected with an easy to plug-in 3.5mm connector. The versatile design of edge® is equally at home in your hand, on a lab bench or mounted on a wall. It simplifies measurement, configuration, calibration, diagnostics, logging and transferring data to a computer or a USB drive.

edge® is the culmination of Hanna’s vision, design capabilities, integrated production facilities, and world class R&D teams. With edge®, Hanna has set the new standard!

Thin, Lightweight Design – edge® is incredibly thin and lightweight, measuring just 0.5” thick and weighing just 8.8 ounces.  It takes up very little space and is easy to carry.


Versatile– edge® ishighly versatile. It can be setup in a laboratory on a benchtop (with its included cradle), attached to a wall (with the included wall mount) or carried by hand like a portable meter.  This convenient design makes edge® perfect for nearly any environment.


Zero Footprint – Using the included wall mount, edge® can be placed on a wall, leaving zero footprint on your valuablelab bench space.


Multipurpose Benchtop Cradle – The included benchtop cradle is engineered to serve multiple purposes.  It not only houses edge®, but acts as a charging station and swivel style electrode holder.


Large, Easy to Read LCD – edge® features an LCD that measures 5.5” and is clearly viewable from over 15 feet.  Add to that a wide viewing angle of 150 degrees and you have one of the clearest LCDs in the industry.


Clear, Full Text Messages – In addition to its large LCD, edge® also features clear, full text guides displayed on the bottom of the screen.  There is no need to decipher scrambled abbreviations; these helpful messages guide you through the measuring process quickly and easily.


Capacitive Touch –edge® features sensitive capacitive touch buttons for accurate keystrokes when navigating menus and screens. Capacitive touch technology allows for a smooth surface without recessed keys that can collect dirt and grime. 


Digital Electrode – You never have to worry about the right angle or aligning pins correctly with edge®digitalelectrodes.  They feature an easy to connect design with a round, 3.5mm digital connection that plugs in quickly and easily, yet firmly. 



Dual USB Ports –edge® can be connected to a computer or USB flash drive for transferring logged data.  It can also be charged while plugged into a powered USB port.



DigitalSensors – edge® features special electrodes that have an easy to plug-in connectionand built-in temperature sensor. All sensors are automatically recognized when connected to the edge®. When a sensor is connected,data including serial number and calibration information is automatically detected and transferred.


Four-Pole Conductivity Probe – Conductivity, total dissolved solids (TDS) and salinity are measured with a four-pole conductivity probe. Four-pole technology allows one sensor to measure over a wide range of conductivity, from low conductivity water to concentrated brine solutions, without polarization effects common with two-pole sensors.


Built-in Temperature Sensor – edge® features a built-in temperature sensor to compensate for differences in temperature. No need to plug in a separate temperature sensor, one connection and one electrode does it all.


Multiple Calibration Points – edge® features multiple calibration points to increase measurement accuracy. edge® can be calibrated up to two points for EC and one point for %NaCl.


Temperature Reference – edge®provides user selection of 20oC or 25oC reference temperature


Auto Ranging– edge®EC and TDS ranges can be selected for manual range selection for measurements to be taken in fixed range, or auto-range selection in which the meter will automatically select appropriate range.


Log on Demand– Log data on demandup to 1000 samples. All readings include date, time and GLP data that can be transferred to a USB flash drive or to a PC as a .csv file (Windows or Mac compatible).


GLP Feature – edge® includes a GLP Feature that allows users to view calibration data, probe ID, and calibration expiration information
