Notes:
(1) Response time to 90% full signal value for applied concentration
(2) Sensor life typical for use at standard temperature and pressure with occasional exposure to gas of interest
(3) Step to 50% LEL within 10 seconds. Recovery to 10% LEL within 30 seconds
(4) Hydrogen tolerent
(5) Diffusion via membrane. Requires electrolyte and membrane replacement every 6 months.
