A4A Precision Pressure Gauge • Solid front protective case • High and low pressure limit stops • Mirror band dial to eliminate parallax reading error • Optional temperature compensation maintains 0.1% accuracy from The Ashcroft precision pressure gauge yields consistent, reliable accuracy through the use of state-of-the-art preci- sion machining and the world's most refined bourdon tube technology. This eliminates the need for a power source and precludes the associated problems such as susceptibility to electronic line noise, power outage or potential fire haz- ard. In addition, this mechanical instru- ment is simple to operate, easy to trouble- shoot, and can be readily flushed or purged to remove foreign matter or trapped gas. Accurate and reliable, the Ashcroft A4A sets a new standard for precision test gauges. Includes Calibration Certificate Traceable to NIST.
