    Low-Pressure Gauges for Chemicals

    A plastic or stainless steel guard, also known as an isolator, protects the gauge from damage caused by corrosive chemicals. Use them with pumps, filters, regulators, and in process lines to measure and display pressures.

    Extreme-Vibration-Resistant Pressure Gauges

    Unlike other gauges that have multiple moving parts that can shake loose, these have only one internal part. They are the most shock-resistant gauges we offer and allow for precise readings in high-vibration applications. Use them with pumps, filters, regulators, and in process lines to measure and display pressure. Gauges meet MIL-G-18997 for resistance to salt spray and washdown environments. They have a safety case that blows out in the back under excess pressure, protecting the operator in front. Mount them with the dial face upright.
