Room pressure does not fail on a schedule. It drifts when doors are opened, when airflow changes, or when power goes doewn. Spot checks only confirm conditions at a single moment in time and leave long gaps with no visibility. When surveyors or infection control ask what happened overnight or over the weekend, manual logs cannot answer that question.
Negative and positive pressure rooms exist to contain risk. When pressure falls out of range, exposure can begin immediately. Without continuous monitoring, facilities teams may not know a the environment was compromised until after staff or patients have already entered the space.
ASHRAE compliance needs environmental control. If pressure or humidity moves out of range, facilities must show when it happened, how long it lasted, who was notified, and what corrective action was taken. Manual readings and paper logs leave too much unanswered during surveys.
When pressure alarms or logs raise concerns, the next question is always why. Was it a mechanical issue, a door left open, or normal room use. Manual checks provide no timeline and no insight, forcing teams to investigate after the fact without reliable data.
Hexmodal Pressure Monitor (HEX-P) provides continuous monitoring of room pressure, temperature, and humidity so facilities teams are not relying on manual logs or local sensors. Conditions are tracked 24/7 and automatically documented, creating a complete record of what happened, when it happened, and how it was resolved. This removes guesswork, closes documentation gaps, and gives teams confidence during surveys and audits.
Mount HEX P in the room and HEX D on the door. No wiring or IT involvement required.
Devices connect automatically through the Hexmodal gateway, which covers up to 250,000 square feet and supports more than 1,000 devices.
The system tracks pressure differential, temperature, humidity, and door position around the clock. Alerts, trends, and excursion events are logged automatically with survey ready documentation in the dashboard.
