See table below.
(Note 1) Reference gas refers to gas other than the component to be measured in sample gas.
("Z" must be specified when interference gas is to be contained.)
(Note 2) The ratio of maximum range to the first range is as given below.
For CO
2
, Ar or CH
4
measurement : 1st range x 5 (times)
For He or H
2
measurement : 1st range x 10 (times) A range from 0 to ...%
cannot be combined with that from 100 to ...%.
1st range < 2nd range
(Note 3) A CO
2
or CH
4
meter needs to be prepared separately.
A reverse range such as 100 to 0% cannot be specified.
Input signal is 1 to 5 V DC.
Adjustment is required at Fuji Electric’s factory.
Details of measurement gas will be checked when receiving an order.
Reverse range such as 100% to 0% cannot be specified.
Cannot be specified if high-speed response is selected.
(Note 4) High-speed response is for H
2
meter used for reference gas N
2
only.
