Capacitance Diaphragm Gauge M-342DG
The capacitance gauge M-342DG is a diaphragm gauge that enables accurate, stable pressure measurement with minimum zero adjustment.
This is achieved using a small silicon MEMS chip as the pressure sensor unit to minimize the influence from the outside environment such as changes in temperature, vibrations, and atmospheric pressure.
