Dwyer differential pressure gauge 2000 series

Dwyer differential pressure gauge 2000 series

MANEHELIC differential pressure gauge

Choose Dwyer’s Magnehelic ® When the differential pressure gauge reaches full scale, it can achieve high accuracy within 2%, and there are over 81 models available for you to choose from. The differential pressure gauge adopts the Dwyer structure, which is simple and wear-resistant Magnehelic ® Moving components can quickly indicate the pressure of very low air or non corrosive gases, including positive pressure, negative pressure (vacuum), or differential pressure. Its design is shock resistant, earthquake resistant, and has the ability to withstand overvoltage. It does not have evaporative condensation, toxicity, or location issues with the pressure gauge liquid; And the price is low.
