Industrial Scientific recommends that any instrument before use receives a functional bump test. Challenging the instrument to a known concentration of gas will verify sensor and alarm operation, providing the user with confidence that the instrument will alarm when in the presence of a hazardous atmosphere. Industrial Scientific offers the bump test gas cylinders of the standard four gases mix of CO, H2S, O2 and LEL to facilitate bump testing. The advantage of using a bumper test cylinder over the conventional calibration gas cylinder and regulator combination is cost and ease of use. 11 Liter size with a 1 year shelf life.
