OMEGA's PX653 Series highly accurate, low-pressure laboratory transducers are designed for clean rooms, HVAC, and laboratory fume hood applications. The capacitance sensor measures dry, clean, non-corrosive gases with a 1 to 5 V DC output and a NIST traceable calibration certificate, providing precise low-range differential pressure measurement.
