Palmer Instruments, Inc. has introduced the "SF" Series Fearless Under Pressure brand of all-stainless steel pressure gauges. The gauges use a special damped movement designed to produce steady pointer action and sharp, legible readings under vibration and pulsation conditions. The result is a low-maintenance dry gauge that performs like a wet gauge. Fearless gauges cannot leak during storage and shipment. Since there is no fill media, crystal fonts can be removed for calibration or replacement purposes while in situ. The gauges also offer a 304 stainless steel case and locking bayonet-type bezel ring. They are offered in 2", 2 1/2", 4", 6" and 10" case sizes. www.instrumentationgroup.comPalmer Instruments, Inc.
