Users of portable gas detectors need to know their units are working properly and will always alarm in the presence of hazardous gases. Wizard gas testing kit allows users of the Tetra four-gas personal monitor to ensure that their instruments remain accurate at all times. The tester automatically applies a standard four-gas mixture to the Tetra to check that each sensor is working within acceptable response limits. If the tester determines that any sensor is outside predefined response limits, it automatically displays a message indicating the need for calibration.
