Gas Testing Kit
November 1, 2004
Crowconâ€™s new Wizard gas testing kit assures users of the Tetra four-gas personal monitor that their instruments remain accurate at all times. The Wizard automatically applies a standard four-gas mixture to the Tetra to check that each sensor is working within acceptable response limits. If a sensor is outside the limits, the need for calibration is displayed. Crowcon Detection Instruments, Milford, OH.
