ABSTRACT:
A gas sampling device whose operation is activated by the blast whose gas to be sampled. This blast activates a switch which in turn starts the operation of a control box which thereafter sequentially outputs pneumatic signals at preset time intervals. These signals are received by a sampling unit assembly which functions in response thereto to receive and retain a gas sample from the blast.
