Many laboratories purchase expensive high-pressure Zero Air cylinders. While this method works, it is safer, more cost-effective and more repeatable to use an in house generator. Your investment will quickly pay for itself.
The Zero Air Generator includes a color-changing moisture indicator to alert you to the presence of water vapor. If water vapor is present, the indicator will change from white to blue. When the water vapor is removed, the indicator will revert to its white color. The ZAG also includes dual pressure regulation for enhanced performance.
