This table-top, pressure gauge calibration stand was designed to calibrate eight pressure gauges from 40,000 psi to 60,000 psi simultaneously.  The stand was built in two sections for increased flexibility.  Each side includes a pump for fast fill and a hand intensifier for extreme pressure accuracy. The operators pressurizes the gauge up to a point and then used the hand intensifiers to increase that pressure one psi at a time. The digital pressure display allows the operator to adjust the settings for maximum accuracy.
