Testing: The Thermocouple and Pirani Gauges

At MHV we test each and every pump that is shipped out of our facility. Testing validates our workmanship has met the standard of quality and that each system performs within specification. For oil booster pumps we conduct throughput testing and on diffusion pumps we...

Testing: The Hot Cathode Ionization Gauge

Gas Ionization gauges enable measurement of pressure at very low densities in atmospheres like those encountered in high vacuum environments. The Hot Cathode ion gauge (Bayard-Alpert gauge) is not a true pressure gauge, it actually measures the particle density using...
