2.5. Internal Components
2.5.1. NDIR Sensor
The NDIR sensor is an internal component that sends infrared light through the sampled gas. The amount of infrared light
that passes through the gas (vs. the amount that is absorbed
by
the gas) provides a complex electrical signature that is used
to quantify the target gas. This component is an 11.5” long cylinder that can be removed and installed in the field, should it
ever need to be replaced. For information on replacing the NDIR sensor yourself, refer to Chapter 6: Maintenance (page 88)
for more information. Alternatively, you can send your H25-IR PRO to the factory or service center to have the NDIR sensor
replaced.
