Multiparameter Meter, edge DO (Dissolved Oxygen) Kit, with Probe, Electrolyte and Membranes, Hanna Instruments, HI2040-01

Hanna Instruments has introduced a new multiparameter meter that is tablet-inspired, and because of its size and specially designed docking station or wall-mounted cradle, it occupies very little bench space in the busy, crowded laboratory!

 

edge® is thin and lightweight, measuring just 1⁄2” 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 can easily be moved from its regularly used lab station to a different temporary location without having to move cumbersome cords to make use more convenient.  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 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!
