Digital Micro Differential Pressure Gauge PCZ-300 Series

PCZ-300 series is high performance micro differential pressure gauge measurable from minimal pressure at 25Pa. By adopting flow sensor instead of diaphragm for pressure-sensing part, superior repeat accuracy is achieved without affected by mounting orientation. And there is no concern over zero drift.

  • Measurable from minimal pressure at 25Pa.
  • High accuracy low pressure area measurement by adopting flow sensing methodological principle. No zero drift.
  • Indicator built-in design suitable for on-site monitoring of air-conditioning, semiconductor facilities or equipment.
  • Bright and viewable large LED display (9999) used, relay contact (two-point) as standard.
