the sensor to ambient concentration, it will
shorten the life of the sensor, but only by about
3 months.
Other instruments with electrochemical
sensors require that you keep the sensor at
<1000ppm all the time, or the sensor will expire
in 3 months. While this is not the case with our
instrument, it is still best practice to limit the
amount of oxygen in the sensor if possible.
If you can, and it is not inconvenient, we do
recommend that you try to flush the instrument
with pure nitrogen and clamp the inlet before
storage. This will extend the life of the sensor
slightly, and make it easier to flush out when
turning the analyzer on and conducting
analysis.
Reduction in the sensor life is more affected by
the amount of time that the instrument is on –
therefore, it is recommended that you turn the
instrument off when not in use.
In other words, if you store the instrument for 2
years, and keep it off, your sensor should last a
total of 7 years from date of shipment.
