2, error: HC ± 10× 10-6( PPM ) Vol ( absolute error ) or± 5% ( relative error)
CO ± 0.03× 10-2( % ) Vol ( absolute error ) or± 5% ( relative error)
CO2 ± 0.5× 10-2( % ) Vol ( absolute error ) or± 5% ( relative error)
O2± 0.1× 10-2( % ) Vol ( absolute error ) or± 5% ( relative error)
NOx ± 25× 10-6( PPM ) Vol ( absolute error ) or± 4% ( relative error)
The above error in one of the requirements to meet.
