If access to standardized CO
2
gas is limited, ambient air can be used to calibrate the High Resolution
CO
2
span. Ambient air should only be used if a buffer tank system is implemented. The buffer tank
system will help stabilize fluctuations in CO
2
levels, providing an ambient air with approximately
400 ppm CO
2
(depending on proximity to urbanized areas).
Tips for Calibrating the F-900 CO
2
Sensor with a buffer system:

The operator should stand away from the F-900.

Use extra tubing to get the intake source away from human breath.

Use a buffer tank system to stabilize the intake source.

Span Buffer Tank System Instructions
1. Find and clean an empty bottle with cap,
which is at least 3L in volume.
2. Drill two small holes in the cap of the buffer
bottle: 1 hole is for the intake tube and 1
hole is for the out tubing.
3. Insert a short plastic tube into the cap of the
buffer bottle for the “out”.
