HI764103 is a digital dissolved oxygen probe with built-in temperature sensor. The current probe has a built-in microchip that stores sensor type, serial number and calibration information automatically detected by the HI98199 portable meter. The sensor features a silver cathode with zinc anode, an integrated temperature sensor and an easy-to-replace HDPE membrane cover.
A built-in microchip stores sensor type, serial number and calibration information including date, time and calibration points. The HI98199 automatically retrieves this information after inserting the probe. The ability to transmit information allows for hot swapping of probes without recalibration. All DO measurements are performed within the probe and transmitted digitally to the meter.
Galvanic techniques measure passively, with the probe spontaneously generating a Voltage based on the dissolved oxygen concentration that passes through the membrane and reacts with the fill solution. Since the reaction is continuous, there is no warm-up time when using an electrical probe.
DO HDPE membranes feature screw-on caps for easy replacement and faster maintenance.
DO measurements are automatically compensated for temperature changes.
