Digital DO Probe
edge® DO probe is highly advanced, featuring a built-in microchip that stores calibration information that is automatically retrieved by edge once the electrode is plugged in. Information stored in the electrode includes model number, serial number and calibration information including the standards used and the date and time the last calibration was performed.
Clark Type Polarographic DO Probe
edge® HI764080 DO probe has an integrated temperature sensor incorporated into the thin ½” PEI body for automatic temperature compensation of dissolved oxygen measurements. The HI764080 probe uses screw on replaceable caps with a PTFE (Polytetrafluoroethylene) membrane that is easily replaced in the field as well in the lab. The supplied HI7041S is a concentrated Potassium Chloride fill solution used with the Clark-type polarographic technology. With this technology, an external voltage is applied to the platinum cathode and silver anode to establish a current that is proportional to the concentration of oxygen in a solution.
