Why is the vacuum on my Micromeritics ASAP 2460 Measuring Instruments making a loud noise?
- Llouis48Aug 5, 2025
If the vacuum system of your Micromeritics Measuring Instruments is making a continuous loud noise, it could be due to several reasons. First, ensure that the sample tube fitting is securely tightened with a wrench. If the noise persists, inspect the sample tube O-ring for wear or cracks and replace it if necessary. Another potential cause is a cracked sample tube, which would require replacement. Lastly, check if a sample tube is loaded on the selected port and that the port valve is closed. If not, install a plug or empty sample tube on the port. If the valve is open, enable manual control and use the instrument schematic to close the gas inlet valve.
