The Omniguard 5 Digital Pressure Recorder is the clear choice for monitoring and documenting vacuum and pressure in a containment area. Ideal for asbestos, lead and mold abatement and clean room monitoring, the instrument utilizes state-of-the-art pressure measurement technology to accurately monitor pressure inside a containment area. It is in a completely self-contained package, designed from the beginning to be extremely flexible yet easy-to-use. The accessories, owner's manual, hose, a spare roll of paper and AC cord, store easily in the lid. In addition, keeping track of an AC adapter is not necessary.

It's easy to find a convenient spot to place the unit since the Omniguard 5 is not position-sensitive and can be hung by a nail. Accurate measurements continue even if the unit is dropped or moved. The backlit graphics display provides the easiest setup possible. Pressure is indicated with large easy-to-read characters and alarm setpoints are always displayed. Screen icons show the monitoring, printer and audible alarm status with a glance.

Detailed information for job setup, feature settings and operating instructions are available on-screen at any time by pressing the Help key. Troubleshooting topics are also covered. Pressure readings are time-stamped and logged into memory once containment has been established. Audible and visual alarms activate whenever the pressure reaches the alarm setpoints. The Omniguard 5 ensures the site inspector that proper containment was maintained. Logs and summary reports can be printed at any time for easy inspection of the monitoring data. Durable and reliable, the Omniguard 5 is clearly the contractors choice for containment monitoring.
