Bootstrap Example

The world’s most innovative pH, EC and DO meter. edge® is thin and lightweight, measuring just 1⁄2” (12 mm) thick and weighing less than 9 ounces (250 g). edge® has an incredibly wide viewing angle, 5.5” (14 cm) LCD and a sensitive capacitive touch keypad. edge® can measure either pH, conductivity and dissolved oxygen through its unique digital electrodes.
