Miniature Pressure Gauges
The small dial on these gauges allows for installation in tight spaces. Use them with pumps, filters, regulators, and in process lines to measure and display pressure.
Gauges with brass case are more impact resistant than ABS plastic-case gauges.

Digital High-Accuracy Pressure Gauges
With Bottom
Connection
A four-digit LCD display allows for easy reading of measurements. The LCD shuts off automatically to extend battery life. Gauges are commonly used with pneumatic regulators, compressors, and in critical processes that require high accuracy, such as hydraulic and laboratory applications.
