Attaching the Sample Probe
The sample probe is used to safely test for gas in confined spaces
before entering.
a
Warning
To measure hazardous gas in a confined space, the
sample probe must be used with the pump module.
Figure 11. Attaching the Sample Probe
a
Caution
To prevent the Teflon lining inside the Tygon tubing from
causing a blockage when connecting it to the sample
probe, the end of the tubing must be flared. Refer to
steps 3 and 4.
1. Deactivate the detector.
2. Attach the pump connector end of the teflon-lined Tygon tubing
to the nozzle on the pump module.
3. Gently insert needle nose pliers into the other end of the teflon-
lined Tygon tubing. Using a circular motion, flare the end of the
tubing.
4. Connect the flared end of the tubing to the sample probe.
Ensure the teflon lining does not separate from the Tygon tub-
ing, as it will block the tube and generate a pump alarm.
5. Activate the detector. Ensure all connections are secure before
sampling.
6. Insert the sample probe into the confined space.
a
Warning
Depending upon the length of the tubing and the type
of gas in the confined space, allow a minimum of
3 seconds per ft. of tubing to ensure the readings
stabilize before entering the area.
Example: 50 ft. = 2.5 minutes
