Review on 📏 UEi Test Instruments EM201B Differential: Accurate Measurement Device for Differential Testing by Tyler Cooley

I have another pressure gauge but it is only accurate to about 0.01psi. inches (about 0.3 inches of water), which is not enough for the measurements I need. This gauge provided reproducible measurements well below 0.001 psi. Customs service. I am very impressed. It comes with a very thick rubber rim that has two powerful magnets built into it. Magnets are very handy for holding the counter on black metal surfaces. The case of the meter itself is made of very thin plastic. This put me off at first, but the rubber binding is so solid that the body material doesn't really matter. I left a voicemail with customer service with a technical question and they actually called me back with an answer. That's unusual these days. The interface is completely intuitive to use, so you don't have to remember or learn anything. They claim it will run for 500 hours on a single 9 volt battery. If he gets 10% I'll be happy and he'll beat my other counter. This meter costs twice as much as the other meter but has much higher resolution and accuracy. I wish I could buy it to start with.
