1.3 Inlet/exhaust connections
The gas cylinder is connected to the gas inlet pipe
À
and the gas exhaust pipe
Á
should be
connected to a suitable length of pipe that vents to outside air. These pipes are long enough to allow
placement to the left or the right of Q-Test.
1.3.1 Inlet Connections
For non reactive gases Crowcon recommend the use of Tygothane or Tygon 3603 pipe. If this pipe is
used, the maximum recommended tube length from the regulator to Q test inlet is 30m.
For use with reactive gases Crowcon recommends the use of Tygothane pipe (AC0301). If this pipe
is used the maximum recommended tube length form the regulator to Q test inlet is 1m.
When using reactive gases, for correct operation, all pipe work and regulators should be purged with
the respective reactive gas.

1.3.2 Regulators
Q-Test can be used with 0.5 litres per min or 1 litre per min regulators. Fixed flow or trigger
regulators are required as the user is responsible for opening the gas flow at the correct time (when
prompted by the Gas-Pro). See accessories section for details.
