Facemasks are single-patient use and
allow the patient to breathe normally
to produce a breath sample. There are
3 sizes: Large, Medium, and Small.

Calibration gas

The GastroCH4ECK® requires
calibration every 4 weeks using 100ppm H2,
100pm CH4, and 20.9% O2, provided as a kit or
replacement cylinder.
