SERIES-200-300 – DURABLOCK® SOLID PLASTIC LOW-RANGE GAS & AIR PRESSURE GAUGES, NIST OPTIONS

Dwyer® Series 200 & 300 Durablock® Solid Plastic Stationary Gages, or draft gages, are offered in inclined and vertical (well-type) styles for highly accurate laboratory or general industrial service, for measurement of low range gas and air pressures, positive, negative or differential. To assure the accuracy required in instruments of this type, all machining of bores and wells is to the highest standards of precision backed by Dwyer’s years of experience in the fabrications of acrylic instruments.

SERIES-200-300 – DURABLOCK® SOLID PLASTIC LOW-RANGE GAS & AIR PRESSURE GAUGES, NIST OPTIONS

The Dwyer Magnehelic® Series 2000 is a versatile analog differential pressure gauge designed to measure air and non-corrosive gas pressures (positive, negative, or differential) with high accuracy and a frictionless movement. The specific model 2000-300MM has a range of 0-300 mm H₂O (millimeters of water column).

The gauge is widely used in industrial and laboratory settings for applications such as:

  • Monitoring filters in HVAC systems.
  • Indicating fan and blower pressures.
  • Measuring duct, room, or building pressures.
  • Monitoring clean room positive pressure.
  • Determining air velocity when used with a Dwyer Pitot tube
Product Overview

SERIES-200-300 – DURABLOCK® SOLID PLASTIC LOW-RANGE GAS & AIR PRESSURE GAUGES, NIST OPTIONS

  • Service: Air and non-combustible, compatible gases.
  • Accuracy: ±2% of full scale at 70°F (21°C) (±3% on -0 models, ±4% on -00 models).
  • Pressure Limits: Standard models are rated to 25 psig (1.7 bar).
  • Temperature Limits: 20 to 120°F (-6.67 to 48.9°C).
  • Housing: Die-cast aluminum case and bezel with an acrylic cover, coated gray to resist corrosion.
  • Weatherproof Rating: Designed to be weatherproof to IP67, resisting shock, vibration, and over-pressures.
  • Connections: 1/8″ female NPT duplicate high and low-pressure taps (one pair side, one pair back).
  • Mounting: Suitable for surface or flush mounting.
  • Movement: Uses a simple, frictionless Magnehelic® gauge movement, which provides quick response to pressure changes and does not require a power source.
