“How many tests can be performed using each canister?”
The instrument manufacturer normally states the gas flow rate required in their operating procedures. Air Products' largest canisters hold approximately 110 litres, so an instrument with a response time of 10 seconds using a fixed flow of gas of 1.0 lpm might be tested several hundred times using the 110L canister.


Periodic testing of portable gas detection equipment is an important element of any safety system designed to detect hazardous gases.
