8.2 Using Gas-Tec in a moving vehicle

Mount the Gas-Tec on a Trigger survey unit (G) to operate from a moving vehicle .
The Trigger Survey System is an integrated system formed when a Gas-Tec is attached
(via quick release fasteners) to a Trigger Survey unit . The Trigger unit contains a sample
boom pump fitted with monitoring electronics, audible alarms and a Sample Boom Kit .
