Technical specifications Version 2.0 Figure 2 shows the response curve of 20 sensors throughout the entire operating range. Sensors are linear throughout the entire range. Fig. 3 Sensitivity Temperature Dependence Figure 3 shows the mean and ±95% confidence intervals of the response of the sensors to 30 ppm isobutylene over the entire temperature range. The temperature response follows the ideal gas law.
