Review on Carburetor Valve Pressure Vacuum Tester by Joseph Rasmussen
Not sure if it measures pressure accurately
I received this product to measure the back pressure in my exhaust. I understand it's not designed for that, but it should be able to measure air pressure no matter where it's coming from. I was expecting the back pressure readings to be at least around 1-2 psi, but they showed less than one wherever I checked. When I blew in I couldn't get it to 2psi either and while I don't know the exact pressure my lungs can generate I was expecting around 5. To sum it up, you don't think it measures pressure accurately.
- Great for outdoor activities
- weak
