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 field 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 flow, from which
the oxygen concentration is determined.
