With accuracy stemming from multi-point factory calibration, pressure transducers, flow sensors, and 40 million cycle valve manifolds, Sentinel Blackbelt Pro measures pressure, vacuum, and flow. Unit integrates eight 24-bit ADCs: 4 to measure test pressure/pressure drop and 4 to measure flow sensor output during flow test. Along with data tracking, auto calibration, and color touchscreen, features include USB, Ethernet, and RS-232 communication and on-board memory for last 1,000,000 tests.
