Specification:

The figure below shows the typical sensitivity characteristic curve, all measured under our company's standard test conditions (refer to the back).
The ordinate represents the sensor resistance ratio Rs/Ro, and the definitions of Rs and Ro are as follows:
Rs = sensor resistance value in various concentrations of gas
Ro = 100ppm sensor resistance in hydrogen
