Hanna Instruments is proud to introduce the world’s most innovative pH meter: edge®. edge’s groundbreaking design is the culmination of Hanna’s vision, design capabilities, integrated production and world class R&D. The edge meter is only 0.5” thick yet rich in features to accommodate the needs of a vast amount of customers. For those that prefer very simplistic operation there is a basic mode operation with a simplified menu and options. For those who require advanced features there is the full featured standard operating mode. The edge HI2020 pH kit can be upgraded at any time with additional probes to measure Conductivity or Dissolved Oxygen.
When used with Hanna’s pH electrodes equipped with a matching pin, edge constantly checks the impedance of the pH measuring electrode to notify you in real time in the event of glass breakage. During calibration, Sensor Check checks the state of the junction. The reference junction is also evaluated and reported on the display.
edge® is incredibly versatile. It can be used in a variety of ways and in a variety of environments without taking up the space of a traditional benchtop meter.
Wall Mount
Using the wall mount cradle (included), edge can be placed on a wall, leaving zero footprint on the benchtop space. The cradle has a built-in connector to power edge and charge its batteries. edge's zero footprint is designed to save you valuable benchtop space.
Cradle and Electrode Holder
edge is equipped with a benchtop cradle with an adjustable swivel electrode holder to charge and hold the edge securely in place at the optimum viewing angle.
edge® is incredibly thin and weighs only 8.8 oz., has an 8 hour battery life, and dual USB inputs.
Two USB Ports
edge includes one standard USB for exporting data with a flash drive and a second micro USB port for you to connect to a computer for file export and for charging your edge when the cradle is not available.
Data Logging
edge allows you to store up to 1000 log records of data. Data sets include readings, GLP data, date and time.
Two Operating Modes
edge can be used in Extended or Basic Operating Modes. Extended Mode enables all features available while the Basic Mode reduces the amount of features to a very simple operation. For example, in extended mode edge offers 5 point calibration with 2 custom buffers while in basic mode calibration can only be performed to 3 points with 5 preprogrammed buffers.
