Gas sensors
The analyser has two types of gas sensors:
1.
The analyser works with a paramagnetic sensor for the Measure-
ment of O
2
(oxygen).
2.
The analyser works with a non-dispersive infrared absorption
measurement. With this measuring principle it is possible to
measure CO (carbon monoxide), CO
2
(carbon dioxide), NO nitro-
gen monoxide), NO
2
(nitrogen dioxide), N
2
O (nitrous oxide) and
SO
2
(sulphur dioxide)
.
