Monotube Humidifiers (MH) Series

The MH Series from Perma Pure is designed for applications requiring precise humidification of gas streams. Common use cases include gas sensor calibration, breath analysis, environmental monitoring, and humidity simulation in research settings. By providing stable and reproducible humidity levels, the MH Series significantly improves the accuracy of sensitive analytical devices. It also plays a vital role in medical and scientific testing environments where consistent humidity conditions are essential.

The MH Series employs proven Nafion™ membrane technology to introduce water vapor into the gas stream in a controlled, selective manner. Operating in a counter-flow of water or steam, the semipermeable membrane transfers only water vapor, blocking particulates and contaminants from entering the gas. This molecular selectivity results in ultra-clean humidification with exceptional stability. Even under fluctuating temperature and flow conditions, the system ensures precise and reliable humidity control.

MH humidifiers provide consistent humidity regulation without the need for power, mechanical controls, or active components. They are available in multiple lengths and configurations, enabling seamless integration into a wide variety of systems. Built from durable, chemically resistant materials, they require minimal maintenance. Their fully passive operation makes them ideal for remote or sensitive applications where system purity and reliability are crucial. Long-term performance is maintained even in challenging environments.
