Profile: Advanced Calibration Designs, Inc. manufactures, distributes, and services the most advanced hand held gas generators available to calibrate corrosive gas sensors. Our products include bump station, Cal 2000 & Cal 101 bump station, mini bump, QC 50 & QC 100, and discontinued products. The bump station combines a weather and corrosion resistant housing with the proven MiniBump to provide a convenient and economical method of testing portable gas detectors. The bump station is designed to work with all manufacturers, not just one specific type like other test stations. This provides the flexibility needed to deal with a variety of users such as contractors. The MiniBump instrument can easily be removed from the Bump Station wall mounting housing to replace the generating cell, or to allow the MiniBump to be used on its own. The housing also has sufficient space to conveniently allow a spare generating cell and batteries to be stored. Our QC-100 from advanced calibration designs provides a quick and easy method of checking the performance of gas detection systems. The QC-100 utilizes revolutionary technology allowing a calibration functional check or "Bump Test" as needed. The unique QuickCheck Vials (QCV) utilize a stable, safe and reliable delivery method allowing ease of shipment, storage and use. The QC-100 is currently available for ammonia and hydrogen chloride, as well as ppm ranges of hexane and toluene.
