Humidifier Tube
A 6 inch humidifier tube comes with any calibration kits purchased
for the Gas Tracer. It is for use in calibrating the ppm combustible gas
sensor. If you did not purchase a calibration kit for the Gas Tracer and
purchased calibration cylinders independently, you will need to
purchase a humidifier tube in order to properly calibrate the ppm
combustible gas sensor. Use the humidifier tube to connect the ppm
calibration cylinder to the Gas Tracer. If you are using a zero air
cylinder to perform a fresh air adjustment on the ppm sensor in Leak
Check Mode or a WET fresh air adjustment in Calibration Mode, you
will need to use the humidifier tube to connect the zero air cylinder to
the Gas Tracer.

NOTE: When removing the humidifier tube from the Gas Tracer or a
demand flow regulator, be sure to grasp it by the clear tubing
at the ends of the humidifier tube assembly, not the
humidifier tube itself.
