Room Pressure Monitors

Designed for critical environments, the AeroMed ISO-Guard™ is capable of extremely accurate pressure differential measurements (to +/-0.0001”wg). Suitable for either negative or positive pressure applications, it is able to display and control room conditions such as pressure, temperature, airflow, and humidity.

ISO-Guard™ has both audible and visual alarms to alert the user to unsafe or undesirable conditions. Available in both flush and surface mount models, you may also choose between internal and remote sensors.
