Reduced Pressure Tester

Reduced Pressure Tester (RPT Test)


Whenever degassing is a requirement of the melting process, it is desirable to verify the effectiveness of the degassing process. Palmer supplies a simple, easy to use partial pressure test unit for this verification.

To use, the operator warms a sample cup, dips the cup into the furnace for a metal sample, quickly places the sample into the vacuum chamber, and starts the vacuum pump.

The aluminum solidifies under a vacuum causing any untrained hydrogen gas bubbles to expand greatly. Once solid and cooled, the sample is cut in half and compared to a gas chart or by using the safer, quicker, and more accurate method of measuring the density of the RPT sample with equipment like the PAS3000 or PAS5000.
