The HI 764080 is a digital dissolved oxygen electrode with built-in temperature sensor. This ultra-thin, Clark-type polarographic electrode is designed for measuring DO in aqueous solutions and contains a built-in microchip that stores sensor type, serial number, and calibration information. The sensor features a platinum cathode with a silver/silver chloride anode, an integrated temperature sensor, and easily replaceable PTFE membrane caps. This probe features a 3.5 mm connector designed exclusively to be used with Hanna Instruments edge® Tablet Meters.
3.5 mm Connector
The built-in microchip stores sensor type, serial number and calibration information including date, time, offset, slope, probe condition and buffers used. This information is automatically retrieved by edge® once the electrode is plugged in. The ability to transfer information allows for hot swapping of probes without having to recalibrate. All DO measurements are performed within the electrode and transferred digitally to the meter. This overcomes any noise issues associated with the traditional high impedance analog measuring system. Electrical noise can be generated from a built in temperature sensor and while working in a humid environment.
The ultra-thin, 12mm, design allows for convenient measurement in narrow vessels such as test tubes.
With screw-on caps, edge® DO PTFE membranes are easy to replace for faster maintenance.
