Applications
• Test, laboratory, and production applications
Special Features
• These Absolute Pressure Gauge pressure elements are capsules up to and including the 50 psia range; 100 psia and above use Bourdon tubes
• In the 50 psia range, pressure is applied to the case and is referenced against the evacuated capsule
• In the 100 psia and above use Bourdon tubes, pressure is applied to a Bourbon tube, which is referenced against an evacuated Bourdon
• Available in 14 standard ranges, these gauges combine aneroid convenience with the accuracy of precision liquid columns

Options
• Calibration in most metric units available at no extra cost.
• Non-linear calibration units are available at extra cost.
• Also available is a compact (12 ¾" H, 12" W, 81/16" D) suit-case type carrying case with the gauge in a shock-mounted panel. The cover is easily removed and pressure connections can be made without removing the gauge from the case.
Ordering Information
When ordering, please specify ordering number, range, and mounting angle. (Extra cost if mounting angle is other than vertical)
Note: Gases must be non-corrosive, no liquid service.
