Ultra-Low Vacuum Gauges
Bottom Connection
Accommodate applications with very low vacuum with these gauges. Use them with vacuum pumps, packaging equipment, and in suction lines to measure and display vacuum.
Gauges with 304 stainless steel case have better corrosion resistance than gauges with steel case.
