Merit's PBX Series 2.5" dial Shock-X™ gauges with brass internals are available in either bottom connection or center back connection. Our Shock-X™ movement provides the vibration-resistant benefits of a liquid filled pressure gauge without the need for glycerin, which adds weight to the product for shipping and the potential for discoloration of the liquid over time, or potential liquid leaks. Accuracy is 1.6% of full scale and the gauges are available in ranges from 30"Hg vacuum up to and including 10,000 psi. Single or dual scales are available as are ranges in psi, Bar and kPa. Custom logo dials are available upon request.
