TECHNICAL INFORMATION FOR TGS2611
2-7 Long-term characteristics
Figure 13 shows long-term stability of TGS2611 as
measured for more than 500 days. The sensor is
usually energized in normal air. Measurement for
confirming sensor characteristics is conducted under
standard test conditions. The initial value of Rs was
measured after preheating for at least three days in
normal air at the rated voltage. The Y-axis represents
the sensor resistance in air, 3000ppm of methane,
3000ppm of hydrogen, 1000ppm of iso-butane, and
3000ppm of ethanol.

The Rs in methane is very stable over the test period.
Figure 14 shows the influence of storage in an
unenergized condition on the sensor’s resistance. The
sensors were stored unenergized in air for 3 months.
During this period, sensors were powered for 1 hour
before measurements in the listed gases were taken.
At the conclusion of the unenergized test, the sensors
were powered under standard test conditions.

This chart demonstrates that after long-term
unenergized storage, sensor resistance would recover
to a stable level within three days of energizing.
