TECHNICAL INFORMATION FOR TGS2600

2-2   Temperature and humidity dependency

Figure 6 shows the temperature and humidity
dependency of TGS2600 in clean air.  The Y-axis
shows the ratio of sensor resistance in clean air under
various atmospheric conditions (Rs) to the sensor
resistance in clean air at 20˚C/65%RH (Ro).

in clean air

Fig. 7 - Temperature and humidity dependency (Rs/Ro)

in 10ppm of hydrogen

Table 1 - Temperature and humidity dependency

(typical values of Rs/Ro for Fig. 6)

Table 1 shows a table of values of the sensor’s
resistance ratio (Rs/Ro) under the same conditions
as those used to generate Figure 6.

Figure 7 shows the temperature and humidity
dependency of TGS2600 in hydrogen.  The Y-axis
shows the ratio of sensor resistance in 10ppm of
hydrogen under various atmospheric conditions (Rs)
to the sensor resistance in clean air under the same
atmospheric conditions (Ro).
