Series 476A Single Pressure & Series 478A Digital Manometer

Digital Manometer Single & Dual Pressure Measurement, Electronic Zeroing, ±1.5% Accuracy

Single & Dual Pressure Measurement, Electronic Zeroing, ±1.5% Accuracy

The SERIES 476A Single Pressure Digital Manometer can be used to measure low pressures from -20 to 20 in w.c. with ±1.5% FS accuracy. The SERIES 478A Differential Pressure Digital Manometer can be used to measure positive, negative, or differential pressures. Both units are constructed of an extruded aluminum case for exceptional durability.

Product Applications

  • Verify field instrumentation performance
  • Adjust fuel mixture on combustion systems
