Easily identify pressure fluctuations with CARBO Instruments pressure gauge. Use our liquid-filled, high-performance psi pressure gauge to monitor fluid, gases, oil and air leaks and buildup of pressure in a system.

Built to last construction: The case of our heavy duty pressure gauge is made of stainless steel with wetted parts of brass and copper alloy. The lens is made of polycarbonate, making it hard to break and scratch resistant

Liquid filled for better performance: Our liquid filled pressure gauge can stand up to shock and vibrations because the internal fluid dampens system pulsation, the gauge can better absorb vibration and pressure spikes.
