7 5 6 4 3 2 1 95 mm 125 mm 137 mm 55.5 mm HI76409 Galvanic DO Probe with Protective Cap The HI76409 is a standard galvanic dissolved oxygen probe for use with the HI9147 portable dissolved oxygen meter. Galvanic probes require no conditioning time and therefore allow the ability to measure instantaneously. With extreme portability and a straightforward design, this probe is ideal for both eld and lab use. The D.O. probe is provided with a membrane covering the galvanic sensors and a built-in thermistor for temperature measurement and compensation. The thin permeable membrane isolates the sensor elements from the testing solution but allows oxygen to enter. Oxygen that passes through the membrane causes a current ¦ow, from which the oxygen concentration is determined. Probe Cable Length Recommended Meter HI76409/4 4 m (13’) HI9147 (meter specific, fixed probe) HI76409/10 10 m (33’) 1 Shielded, waterproof cable 2 Flex protect 3 Strain relief for cable 4 Temperature sensors 5 Zinc (Zn) anode 6 Ag + cathode (3.5 mm), pure silver 7 Protective cap HI76409A/P Easy, Screw Cap DO Membranes Have HDPE DO replacement caps available when DO measurements become sluggish or for routine maintenance. HI7040 • HI7042 DO Solutions It is crucial to the performance of your DO probe to keep the sensor active with regular maintenance.
