Ordering information
When ordering, please specify ordering number, range, and mounting angle. (Extra cost if mounting angle is other than vertical)
Options
Calibration in most metric units available at no extra cost. Non-linear calibration units at extra cost.
Also available is a compact (12¾" H, 12" W, 81/16" D), suitcase-type carrying case with the gauge in a mounted panel. The cover is easily removed and pressure connections can be made without removing the gauge from the case.
Note: This gauge should not be used for corrosive gases or for liquids of any kind
