Review on High-Quality Stainless Pressure Gauge for Accurate Hydraulic Test, Measure & Inspect Pressure & Vacuum Levels by Mark Jefferson

Nice, easy to read dial. If you're in a low-vibration environment you can buy it cheaper, but when vibration is present (such as when installed next to a compressor) the liquid fill dampens most if not all of the needle's vibration. Looks very well made, has been in use for 10 years and is still as accurate as the day I installed it.
