Product Description
The Hanna edge is thin and lightweight, measuring just ½ in. thick and weighing less than 9 ounces. edge has an incredibly wide viewing angle, 5.5 in. 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 a serial number, and they connect 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. edge 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 electrode you are using is not clean or if your buffers are contaminated during calibration. We have also added to CAL-CHECK for sensors with matching pin: now it warns you if the pH bulb is cracked, and if the junction of the electrode is compromised.
The electrodes used with edge are nearly as advanced as the edge itself: featuring a built-in microchip that stores sensor type, ID, and calibration information that is automatically retrieved by edge once the electrode is plugged in.
Stored pH calibration information includes: calibrated buffers, date, time, offset and slope characteristics of the electrode. Conductivity calibration information includes: calibrated conductivity standards, date, time, and cell
constant of the sensor. Dissolved oxygen calibration information includes: standards used for calibration, date, time, altitude and salinity correction.
These digital electrodes also feature an easy to plug in 3.5 mm connector so you never have to worry about the right angle or aligning pin settings.
