Review on Portable Pressure Measurement Measuring Momenturn by Tim Shah

Sturdy construction, large numbers and easy to read. This one uses AAA batteries, not expensive 9V batteries. It has the weight I need and a backlit display. Yellow is easy to find in low light. An economical and scientific way to measure the effectiveness of my car soundproofing project, i.e. before and after soundproofing. Thanks very much!
