Dwyer Gauge Quality with Surprising Affordability

Transcat is your source for Dwyer’s broad line of affordable Magnehelic gauges that are trusted for guaranteed accuracy within 2 percent of full scale. These shock-resistant pressure gauges quickly deliver positive, vacuum or differential pressure readings of cleanair or non-corrosive gas. They demonstrate the simplicity of the brand’s frictionless, fluid-free designs. Contractors and HVAC pros commonly rely on Magnehelic pressure solutions for:

  • Filter and blower vacuum monitoring
  • Fan pressure indication
  • Clean room positive pressure indication
  • Duct, room or building pressure measurement

The Series 4000 Capsuhelic differential pressure gauge also indicates with accuracy rapidly and is suitable for internal measurements up to 500 psig. What can a Capsuhelic do for you?

  • Read pressure, vacuum or differential pressure
  • Measure fluid flow, filter pressure drops and liquid storage tank levels
  • Provide frictionless movement, with measured pressure encapsulated
  • Support full scale readings as low as 0.5 in H2O

One Tool, All-around Functionality

Are you looking for a multifunction instrument to save you time, space, and expenses while supplying critical control functionality? Dwyer delivers devices that unite multiple control functions – and the Series 3000SGT Photohelic Switch/Gauge/Transmitter is the perfect example.

  • Connect one set of pneumatic lines versus three or four
  • Rely on the integrated Magnehelic Gauge to measure low air pressure
  • Read positive, negative or differential pressures within ±2% of full scale accuracy
  • Gain a 4-20 mA, 2-wire transmitter that operates off external power

Mastery of Switch and Meter Designs

The precision instruments from Dwyer are full-featured and reliable, and this includes the:

Rate-Master – Classified for general use, the Rate-Master Flowmeter is designed for accuracy and repeatability in compatible liquid and gas readings.

Flotect Flow Switches – These compact switches dependably monitor liquid, gas or air flow. The V6 switches are magnetically actuated, simplifying operations.

Manometers – Dwyer continues to advance its digital manometers with specialized features and highly accurate sensors. If you’re a maintenance technician, Dwyer has a manometer for capturing pressure, flow and velocity with precision accuracy.
