pages. They include the rotary geared stainless steel movement, the all 316 stainless steel pressure system, the phenolic turret case, numerous other improvements and most recently, the patent pending Duragauge®PLUS!. Several important variables must be considered when selecting the type of case for the application. A gauge is subject to environmental and atmospheric conditions, and the gauge internals must be protected from these elements.
Warranty & Movement Ashcroft® Duragauge® Pressure Gauge Edward Ashcroft introduced the Bourdon tube pressure gauge to American Industry 140 years ago. Since that time, we have developed thousands of improvements and over a hundred patents furthering the development of Ashcroft pressure instruments. From the very beginning, we have maintained our reputation for quality, product performance, and technical innovation that is the envy of all others in the industry.
Other Duragauges Ashcroft® Duragauge® Pressure Gauge PPerLfoUrmSan!ce PLUS!™ Performance Duragauge® An exclusive, new, optional feature provides virtually liquid-filled performance in a dry gauge. The Ashcroft PLUS!™ feature is a patent-pending design incorporated into the industry-standard Ashcroft pressure gauge. PLUS! is available in any Duragauge case style material or range. Historically, pulsation and vibration have reduced gauge life and made gauges difficult to read.
