Dwyer differential pressure gauge 2000 series

Dwyer differential pressure gauge 2000 series

MANEHELIC differential pressure gauge

When choosing Dwyer’s Magnehelic differential pressure gauge at full scale, you can achieve high accuracy within 2%, with over 81 models available for your needs to choose from. The differential pressure gauge adopts a Dwyer structure with simple and wear-resistant Magnehelic moving parts, which 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.
