The Agilent IMG-100 Inverted-Magnetron gauge tubes produce accurate, repeatable pressure readings and may be used in dirty or corrosive applications. Their measurement performance is similar to Bayard-Alpert gauges, but like cold-cathode gauges they are easy to clean and repair, without the limitations that most cold-cathode gauges have.

The Agilent IMG-100 can measure pressures in a range comparable to most glass hot-filament gauges. This passive high vacuum gauge is perfect for use in vacuum furnaces and other industrial systems, where ruggedness is of prime importance.
