Summary

Our customers tell us that we do humidity control for controlled atmospheres better than anyone in the industry!!  Depending on the target application, we can provide systems that operate in either a relative humidity mode or an absolute humidity mode.  Our relative humidity modules deliver a 100%RH at the target dewpoint and are available with an optional gas divider system to allow the unit to deliver 0-100% RH with a response time of only a few seconds.

If ultra stability is what you need, we have precision systems that can hold the target dewpoint to within 0.01°C !!

Systems are also available with temperature monitoring and control, pressure monitoring and control, and a wide array of inputs and outputs for tight integration with whatever process is at hand.

Fideris physical process control and monitoring modules are a natural fit to many environmental chamber atmosphere control applications. Our turn-key systems can control not only the gas mixture and humidity, but also chamber temperature and pressure. Additional modules can control fans, pumps, drains, ambient monitors, and any other component utilized in your controlled atmosphere system.
