HI-76409/4 Galvanic Dissolved Oxygen Probe, 4m with Built-in Temperature Sensor
HI-76409/4
Galvanic DO Probe with Built-in Temperature Sensor, 4 m cable for HI-9147.
Hanna Dissolved Oxygen probes are extremely rugged and perfect for laboratory and field applications. The HI-76409/4 is for use with the HI-9147 and has a 4m cable.
The HI-76409 is a standard galvanic dissolved oxygen probe for use with the HI-9147 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 field and lab use.
The DO 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 flow from which the oxygen concentration is determined.
