Infinity Tools 1.5吋真空計 附黃銅接頭 用於文氏管系統

The needle settled instantly and held steady once I dialed in the venturi switch, which is exactly what I needed. The 1.5" face is easy to read from across the bench, and the brass t-fitting feels solid enough to outlast the rest of my setup.

The brass fitting threaded on perfectly to my venturi setup without any sealant needed. The gauge needle responded instantly when I started the system, and it’s stayed steady through three cycles.

The 1.5-inch face is easy to read even from a few feet away, and the brass fitting felt solid when I tightened it onto the venturi system. Hooked it up in under five minutes and the reading stayed steady the whole time.
