Review on 🔍 HFS Pressure Gauge Test, Measure & Inspect - Vacuum-Filled by Roberto Manzer

Appears to be a well made sensor. I can't speak for accuracy as I don't have a proper standard to rely on, but it seems reasonable. The only reason the 4 stars are easy to read is because I feel like a little more liquid could be added to the gauge which would reduce the size of the air bubble at the top and make the most important segment easier to read. Some bubbles must be allowed to allow for thermal expansion. Otherwise, this is a good indicator, especially for the money.
