DESCRIPTION:
Hanna Instruments is proud to introduce the world’ s most innovative pH, EC, and DO meter... edge™ .
edge is thin and lightweight, measuring just 1D2” thick and weighing less than 9 ounces. edge has an incredibly wide viewing angle, 5.5” LCD and a sensitive capacitive touch keypad.
edge measures pH, conductivity and dissolved oxygen through its unique digital electrodes. These digital electrodes are auto-recognized. Providing sensor type, calibration data and serial number when connected to edge with an easy to plug-in 3.5mm connector. edge’ s versatile design 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 features Hanna’ s exclusive CAL-CHECK® to warn you if the pH electrode you are using is not clean or if your buffers are contaminated during calibration. Indicators are also displayed for response time and probe condition that is based on the offset and slope of the electrode. We have also added to SENSOR-CHECK for sensors with matching pin: now it warns you if the pH bulb is cracked or if the junction of the electrode is clogged.
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!
