-
How do I clean the sensor on my Just Better (JB) DV-22N vacuum gauge?
Use 90% pure or better isopropyl (rubbing) alcohol. Do not use denatured alcohol. Pour a small amount into the sensor area to clean it, as residues can cause erratic readings.
-
What kind of vacuum pump oil should I use?
It is recommended to use high-quality vacuum pump oil. If your pump fails to pull down to at least 50 microns, the oil is likely contaminated and should be changed immediately.
-
How often should I change the oil in my vacuum pump?
Oil should be changed if the pump cannot reach the desired deep vacuum (50 microns). For best performance, check the oil quality before every job and change it if it appears cloudy or contaminated with moisture.
-
What is the best way to check for leaks during evacuation?
Using a tool like the DV-29 creates a closed environment to isolate the system. If the micron reading rises slowly, it may indicate permeation or a leak. Using O-ring sealed couplers helps prevent leaks at connections.
