How does a vacuum gauge work?
- A vacuum gauge measures the negative pressure or vacuum level in a system by detecting the amount of air or gas remaining in a closed space.
- Analog gauges use a mechanical dial to display pressure readings
- Digital vacuum gauges use electronic sensors to provide high-precision micron-level measurements
- Micron gauges are used for deep vacuum measurements to detect moisture and leaks in refrigeration systems
- ▼
How to use a vacuum gauge for HVAC?
- Using a vacuum gauge for HVAC evacuation ensures the system is free from moisture and contaminants.
- Connect the vacuum gauge to the service port of the refrigeration or AC system
- Attach a vacuum pump and start the evacuation process
- Monitor the vacuum pressure until it reaches the desired micron level (below 500 microns for HVAC)
- Perform a standing vacuum test to check for leaks or moisture contamination
- If the vacuum holds steady, the system is ready for refrigerant charging
