PY801W Micro Differential Pressure Calibrator

PY801W Micro Differential Pressure Calibrator is a portable multifunction calibrator specifically developed for the calibration of micro pressure and differential pressure instruments. It combines high-accuracy pressure measurement, electrical signal calibration, HART communication and 24 VDC loop power in one compact handheld device.

Designed for pressure ranges from ±10 mbar to ±1 bar, the PY801W is suitable for calibrating differential pressure transmitters, micro pressure gauges and low-pressure process instruments. It is widely used in HVAC systems, cleanroom monitoring, pharmaceutical manufacturing, filter performance testing and other industrial applications where precise low-pressure measurement is required.
