Gas Detection

Instrument calibration and bump testing

The periodic function, or bump testing, and calibration of gas detection equipment is critical to workforce safety and plant protection. Air Products’ Experis® range of speciality gases deliver certified, traceable, and stable mixtures in a wide range of package options to support this application.

The most popular choice is the non-refillable, or disposable canister, favoured for its ease of use and portability. Canisters enable tests to be carried out in the field as well as in the workshop

The Experis® range of gases incorporates all the most commonly used calibration gas mixtures.

Business Development Specialist

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.
