OneVue Sense Differential Pressure Sensor

Our highly accurate OneVue Sense Differential Pressure Sensor requires a minuscule amount of air flow through the unit to detect pressure changes, making them ideal for monitoring AIIRs, operating rooms, construction zones, and other critical environments.

Providing an effective, yet adaptable containment solution for COVID-19, OneVue Sense Differential Pressure Sensors are portable and easy to install. Download our Installation and Use FAQs PDF to learn more.

A New Level of Assurance

Maintaining strict air pressure differentials in specific healthcare environments is essential to the safety of your patients. While positive pressure is required in operating rooms, compounding and sterile processing areas, and protective environment rooms to keep contaminants out; negative pressure is needed in isolation rooms and construction/renovation zones to prevent contaminants from spreading throughout the facility. With OneVue Sense Differential Pressure Sensors, you’ll be able to continuously track and document the pressure in these rooms. More importantly, you'll be notified immediately if the pressure changes to ensure the safety of patients and keep your facility in compliance.

  • Provides readings in inches of water (inches H2O) or Pascals (Pa)
  • LCD screen with intuitive graphic display shows pressure differential to ± .001 inches H2O (± 2.0 Pa)
  • Customizable pressure threshold settings help minimize “nuisance” alarms
  • Configurable sensor automatically captures and documents pressure readings, eliminating manual reading errors
  • NIST Traceable sensing element meets compliance standards
