Ashcroft 1082 AS Bronze Test Gauge Vacuum-400 PSI

This device permits precise adjustments to achieve exact span calibration from 0 to 100% of scale. The micrometer screw attached to the slide will vary the span by approximately 1⁄2% per 360° rotation.

The long life bourdon tube is capable of sustained accuracy, yet is suitable for process applications. The Ashcroft test gauge uses the Ashcroft Duragauge® pressure gauge bourdon tube – perhaps the most highly developed bourdon tube in the world. Proven and refined by years of rugged service in demanding process applications around the world, this outstanding pressure element is standard in all 4 1⁄2,˝ 6˝ and 81⁄2˝ size Ashcroft test gauges.

Hydraulically staked movement provides improved stability. The movement, with Teflon® coated gears and bearings, uses a unique hydraulic staking operation to ensure a rigid movement frame that resists shift due to shock and vibration. High and low pressure movement stops are standard to protect the gauge against calibration shifts caused by accidental overpressure, and to limit pointer rotation. Improved dial and pointer results in excellent readability. Larger numerals, additional graduations and a highly polished mirror band combined with a knife edge pointer with red painted tip to allow precision readability that eliminates parallax error.

 

Test gauges are built in a modern manufacturing environment. Assembly, calibration and inspection are performed in a climate controlled manufacturing cell to ensure consistent product quality. Computer set pressure standards give accurate calibration that is traceable to NIST (National Institute of Standard & Technology – formerly NBS). A skilled technician is responsible for building, calibrating and final inspection of each test gauge. The technician’s signature attached to the gauge guarantees ASME B40.1, Grade 3A (0.25%) full scale accuracy.

 

The standard test gauges are now available from stock. The new standard 4 1⁄2,˝ 6˝ and 81⁄2˝ 1082 gauge line is supplied with solid front case for safety. Corrosion resistant black epoxy finish is standard.
