Omniguard 4 Open

OmniGuard 5 Differential Pressure Recorder Cellular Modem Manometer

The Omniguard 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 Omniguard utilizes state of the art pressure measurement technology to accurately monitor pressure inside a containment area.

We've taken everything we've learned from over 20 years of making pressure monitors and put it into the Omniguard. The same great ease of use, accuracy, versatility and reliability you've come to expect from a product bearing the Omniguard name, with the new features you've asked for.

With the addition of a touch screen interface, set up and navigation of the Omniguard has never been easier. The 4.3" Color LCD is much larger than the previous screen and now also has color indicators bordering the LCD screen make it easy to see the status of the monitor even from a distance.

The touch screen navigation has greatly simplified the set up and usage of the Omniguard. The user-friendly interface makes it easy to move from menu to menu and quickly access the information you need.

The Omniguard now offers 4MB of logs space, which will hold 6+ months of normal job logs. That's 8x more than the previous version of the Omniguard. You can also access and download specific job logs with ease. You no longer have to download all the job logs on the Omniguard. Plug in your USB flash drive to pick and choose specific days/weeks/or whole job logs to download.

You never need to worry about a short loss of power disrupting your ongoing job log. With a built in Lithium Ion battery, the Omniguard now supports up to 6 hours of operation without AC power.

Now with an international power supply that operates from 80-240VAC, 50-60Hz, the Omniguard can operate around the world with no modifications. The Omniguard is now multi-lingual; easily switch between English, French, or Spanish.

We continue to offer the functional self-contained design so there are no AC adapters to lose or hoses to keep track of. Everything fits inside the case so you can protect your investment from damage by operating the Omniguard with the lid closed.

The Dual USB ports continues to make collecting and viewing your job logs quick and easy. You can download and view logs using your computer's USB port and our free software. And you can now monitor the current status and change the setup directly on your PC. If you are on site you download job logs directly to a USB flash drive at the job site. You can view and store the logs later on your PC.

The Omniguard uses the same accessories, and cables as the Omniguard 4, so your investment in accessories is not lost.

With features designed to display information clearly and quickly, you'll be confident that you have the best instrument for the job.

Omniguard 4 Open

Easy To Use

The Omniguard is a differential pressure recorder in a completely self-contained package, designed from the beginning to be extremely versatile yet easy to use. The included accessories, owner's manual, hose, a spare roll of paper and AC cord, store easily in the lid. There's no AC adapter to keep track of.

It's easy to find a convenient spot to place the unit since the Omniguard is not position sensitive and can be hung by a nail using the built in hanger. Accurate measurements continue even if the unit is repositioned or moved. The 4.3" color 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, and troubleshooting tips are available on-screen at any time by accessing the Help menu. 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 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 is clearly the contractors choice for containment monitoring.

Easily navigate the menus and settings using the user-friendly touch screen interface.

The intuitive lay out and menu orientations mean you can quickly and easily set up and start a job. Touch the icons on the home page to adjust their correlating set points, and use the alpha numeric key board to personalize the contractor and job names and password protection settings.

Multiple screens allow the user to easily inspect and adjust the settings for specific job requirements.

Easy To Read

The Omniguard comes equipped with a thermal printer that provides a detailed, easy to read log of the pressure in the containment area as well as recording any changes made to the setup. Retrieving the data log is now quick and easy and more comprehensive than ever before. Touch the printer icon to bring you to the Printer Settings Menu, choose from any job log stored on the Omniguard, then choose to print the log from today, the last 24/48/72 hours, or the entire log. You now also have the option to view the log directly on the screen, rather than printing the entire log.

Each of these reports offers the user specific, pertinent information and a hard copy record of the data logged from the containment area.

Each printout provides a summary of the current job status, including the amount of time in Normal Operation, the number of Alarms and the amount time in Alarm Conditions (if any) along with an area for sign-off. In addition, a Configuration Report can be viewed and printed from the Printer Settings Menu. The Configuration Report provides a hard copy of all of operational settings, memory usage and log space available.
