Empty box barometer is a kind of atmospheric pressure measuring instrument with deformation element as induction, which is widely used in meteorology, aviation, aerospace, military, agriculture, and scientific research and other fields. The empty box barometer verification device can verify and calibrate it to ensure the accurate value of the empty box barometer.

HSIN empty box barometer verification device is a professional equipment for calibration and verification of absolute pressure instruments such as empty box barometers. The verification range is (300~1100) hPa. It supports digital air pressure sensors and empty box barometers. Vacuuming under atmospheric pressure and adding positive pressure under atmospheric pressure, the operation is simple, stable and reliable, and the verification data format is standardized, which meets the actual needs of metrological verification work.
