High-accuracy capacitance diaphragm gauge  


High-accuracy capacitance diaphragm gauge (F-tron series)

•Features and application
Resolving power of display: 6 1/2 orders of magnitude (digits)
      (about 2 digits improved vs. conventional)
   Precision: 0.1% R
   Notable improvement in noise resistance due to pulsed signal transmission
   High-speed data communication and automatic zero-point correction possible
   1/2 or less of unit volume vs. conventional
   Process pressure monitoring for film-making device
   Pressure monitoring for gas-replacement and gas-inclusion
   Pressure monitoring for vacuum distillation, drying, etc.
