ME Dryers

Whether you call it moisture or humidity, dew point or condensation. Sometimes, it is essential, but often, it is a barrier to accurate breath analysis. In designing medical equipment, it is not enough to just manage moisture. You need to control it. At Perma Pure, we have worked to give you that control for the past 40 years. 

Perma Pure’s ME Dryers, built with Nafion™ Tubing, remove moisture in a variety of medical market segments, enabling accurate analysis and protection of sensing mechanisms. Controlling humidity is a key element in providing the best care to the most vulnerable patients.

Address Moisture Challenges

Continuous Monitoring
Medical professionals are increasingly using breath to monitor patients. However, if patient breath is not conditioned properly or if not attended to, humidity can affect the accuracy and timeliness of the results.

Respiratory Diagnostics
Several researchers have tested patient breath to diagnose and monitor a variety of issues, including asthma, gastrointestinal issues and cancer. However, moisture in our breath tends to decrease the life of typical filters used in outpatient breath analysis devices.

Gas Therapies
When delivering therapeutic gases to patients, it is important to confirm the amount of gas present. Humidity can impact measurement of gas.
