PERFORMANCE
For test purposes, all data taken using the following conditions:
- SGX linearisation and temperature compensation algorithms; see Infrared Sensor Application Notes.
- Lamp modulation 0.4 - 5.0 V, square wave, at 4 Hz and 50% duty cycle.
- Ambient temperature (20°C) and pressure (103 kPa).
- All gases diluted in dry nitrogen.

Note 1: The resolution will vary with gas concentration due to the non-linear response to the target gas, therefore the best resolution will be at the low
concentrations and will get worse as the concentration increases.
HANDLING PRECAUTIONS
1. Do not allow sensors to fall on the floor. This could cause lamp filament breakage, damage to the pins and the gas entrance
aperture.
2. Do not apply mechanical force against the gas entrance aperture.
3. Do not immerse sensors in water or other fluids.
4. Protect the gas entrance aperture against dust ingress and sprayed materials.
5. Anti-static handling precautions must be taken.
