Product Options

Option of Relays:
This is a Pirani Capacitance Diaphragm Gauge (EQ-PGC-554) combines the patented ceramic capacitance diaphragm sensor technology with the advantages of a Pirani gauge in a single product. In the measurement range between 10 mbar and atmosphere, the capacitance diaphragm technology provides gas-type independent, highly accurate values for reliable pressure measurement.
   With the need to factor gas type dependency into the pressure reading output being eliminated, risks of explosions in tube vessels or other chambers due to incorrect display of pressure AND/OR negligence of adjustment for gas types ARE GREATLY REDUCED.


    • Designed and made by Switzerland-based INFICON
    • Gas-type independent above 10 mbar - allows safe venting with any gas mixture
    • High accuracy and reproducibility at atmosphere for reliable atmospheric pressure detection
    • Fast atmospheric detection eliminates waiting time and shortens process cycle
    • Versatile mounting orientation provides engineering freedom in tool design
    • Sensor is fully ceramic coated.
    • Easy to exchange plug & play sensor element with onboard calibration data guarantees high reproducibility and low cost of ownership        
    Power Connection
    • 9 pins D-sub connector. 
    Power Adapter
    • One 15 VDC power adapter is included and ready to use. Input voltage for the adapter is 110~240 V.
    Measurement Range
    • 3.8E-5 to 1125 Torr.
    • 5×10-4 … 1×10-3 mbar (N2) ±50% of reading
    • 1×10-3 … 100 mbar (N2) ±15% of reading 
    • 100 … 950 mbar ±5% of reading 
    • 950 … 1050 mbar ±2.5% of reading 
    • Digital display (20x14 mm) with measurement unit Torr 
    Gauge Fitting
    • Small Foot-Print with KF16 port
    • 46 mm×28 mm×126 mm (L x W x H)
    Shipping Weight
    • 5 lbs
    • One year limited manufacturer warranty, please contact for information.
    • Please note the sensor is consumable and not covered by the warranty. In the case of severe contamination or malfunction, the sensor can be replaced, please read the instruction for details. Replacement sensor is offered at $574/each)
    • The pressure gauge is manufactured calibrated base on PTB / METAS (German / Swiss NIST) standards. Calibration data is available upon request.
    Application Notes
    • General vacuum measurement and control in the Medium Vacuum Range (Range 1.0E-4 Torr to ATM).
    • Pirani gauges used in a clean environment can effectively operate above 5.0E-5 Torr range. 
    • If your tool requires effective reading in the 1.0E-5 Torr or lower, please select Pirani/Cold Cathode gauge with measurement range from 3.75E-9 to 760 Torr
    • Optional: M14 to KF16 adapter is needed for the use with MTI vacuum flanges, please click left picture below to order replacement part.
