What is the Supco VG 640 vacuum gauge used for?

The Supco VG 640 measures vacuum levels in HVAC systems during service, installation, and commissioning. It monitors 50 to 2000 microns with ±10% or ±10 micron accuracy, enabling technicians to verify proper evacuation and system integrity before refrigerant charge.

What are the specifications of the Supco VG 640?

The Supco VG 640 measures 50 to 2000 microns with ±10% or ±10 micron accuracy and 0.5 sec update rate. It operates from -17°C to 65°C, produces an 87 dB alarm, and is designed for rapid, real-time vacuum monitoring in HVAC service workflows.

Where can I buy the Supco VG 640 in Singapore?

3G Electric supplies the Supco VG 640 (SKU: COP18012) to Singapore and Southeast Asia. We source the gauge internationally, manage customs clearance, and handle door-to-door delivery. Contact us for availability and lead times.

How do I use a vacuum gauge like the Supco VG 640 in HVAC service?

Connect the VG 640 to the system's low-side port via a manifold or evacuation line. Power it on and monitor the micron reading as your vacuum pump evacuates air and moisture. Once the gauge reaches your target micron level (typically below 500 microns), the system is ready for refrigerant charging.
