Repeatability: (Note1)
Ϯ1 vol% H

O (sample gas pressure 2 kPa or less)
Linearity: (Excluding standard gas tolerance)
(Note1)
(Use oxygen of known concentration (in the measuring range) as the
zero and span calibration gas.)
Ϯ2 vol% H

Ϯ0.49 kPa)
Ϯ3 vol% H

Response Time: Response of 90 % within 5 seconds. (Measured after gas is introduced
from calibration-gas inlet and analog output starts changing.)
(Note1) These tolerances do not apply to the pressure compensated
version, or where natural convection is used for the reference air.
