edge® pH digital meter is packed with many cutting edge features to ensure accuracy and usability.
Digital pH Electrodes
edge pH electrodes are highly advanced, featuring a built-in microchip that stores calibration information that is automatically retrieved by edge once the electrode is plugged in. With a digital electrode, it is possible to change electrodes without having to recalibrate since the calibration information is stored in the pH electrode and not the pH meter. This allows flexibility for the user that measures pH with more than one electrode. (ORP electrode sold separately).
Hanna’s exclusive CAL Check feature analyses the pH electrode response in the pH buffers during the calibration process to alert the user of potential problems such as contaminated buffer and clean electrode. After calibration, indicators for probe condition and response time are displayed on the measurement screen.
When used with Hanna’s 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.
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.
edge digital pH meter 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.
