Figure 1
- The response (dR/Ro) of a sensor to 5 ppm of hydrogen sulfide in air is a maximum at 322°C. The signal is greatly reduced at higher and lower temperatures.
-
Figure 2
- Figure 2 – Speed of response and precision of temperature control are greatly enhanced by the ASL digital system.
-
Figure 3
- Figure 3 – The temperature of peak response of the imaginary component of the impedance (at 300 Hz) to 5 ppm hydrogen sulfide is at a higher temperature than that for the resistance response (Figure 1).

Figure 4
- Figure 4 – Response of the resistance of a sensor to alternating pulses of 20 ppm and 5 ppm hydrogen sulfide.
