Omniguard 4 Open

The Omniguard 4 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 4 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 15 years of making pressure monitors and put it into the Omniguard 4. 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.

We started with a self contained design so there are no AC adapters to lose or hoses to keep track of. Everything fits inside the new improved case just like before, only now you can protect your investment from damage by operating the Omniguard with the lid closed. The easy to use graphical interface is still there but you'll have a bigger screen with a white backlight for better viewing.

You can download and view logs using your computer's USB port and our free software, and with the Omniguard 4 you can also monitor the currrent status and change the setup directly on your PC.

For 2009 we've added a second USB port that lets 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. No more carrying your laptop around to collect logs or bringing you Omniguard into the office to hook up to the computer.

The new USB port also gives you the ability to connect your Omniguard 4 to an external cellular wireless modem. This lets you automatically send alarm warnings and daily job summaries to wireless phones and email accounts. In addition the Omniguard will respond to requests for information from wireless phones and via email, giving you instant access to the current status as well as job summaries.

If you need to retrieve your Omniguard's job logs remotely you can connect an external telephone modem instead. You'll be able to download the complete log from anywhere using your computer and a phone line.

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

You can learn more by going to the details and specifications pages or by downloading a brochure.

Designed to be the most reliable long term monitoring recorder in field, the Omniguard 4 offers compact design, ease of use and durability that will last from job to job.
