Fig.9 TGS #813 HUMIDITY DEPENDENCE IN AIR CONTAINING VAkIED
CONCENTRATIONS METHANE.
Test condition:
Vc 1OV A.C. / VH 5.0V A.C. / RL 4KR
Atmospheric condition:
Humidity is changed at a fixed temperature
of 40°C.
Measuring procedure:
At respective humidity conditions, wait
for Outputs in air to stabilize and measure
Outputs in gas.
Following each changed of
humidity allow 2~3 hours for Sensors to
stabilize at the new test conditions.
The data shown is the average ratio of five Sensors resistance at
various humidity levels relative to Sensor resistance at 0% R.H.
measured at 1000, 2000 and 3000ppm of methane.
