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 10 ppm isobutylene over the entire temperature range. The temperature response follows the ideal gas law PID-AY5 Replacement Parts/Consumables List Part Number Part Number Maintenance Kit, which includes: 2 ea Polishing Disc 2 ea 10 μm, Cloth, Bottom Filter 2 ea 1 μm, Teflon, Top Filter, Large...
