Digital HVAC Gauges,R410A R134A Digital Vacuum Pressure Manifold gauges Set with 90 Refrigerants Leak Detection Mode (Dual Test Data)

Excellent product. Very useful 🤩

My husband worked on R134A. He said It is accurate, easy to operate, easy to read. The hanger design is good, very helpful hanging anywhere close by when he work. It is convenient to have this tool . Recommend.

I will set it at 0 and leave it for a few minutes and it reads 20 psi or -8 it doesn't hold true. I used them on my truck and I kept adding more freon but the pressure kept dropping, lucky for me I had my old analog and used those instead. I was hopeful they would work but they did not.

Muy bueno realmente

Para mi trabajo si es eficaz para aquellos que buscan algo más preciso. Le doy un 10 a la herramienta. Aquí en México Excelente, saludos!

Conectores de mangueras no sellan, hay que aplicar mucho torque para que sellen no fugue el gas, calibración entre manómetros es diferente, cuando uno está en cero psi el otro marca 5 psi
