 Standard Magnehelic ? type pressure gauge with large easy to read 4 "dial 
 Dimensions, standard gauge 2000 series Magnehelic ? 
 (In a slightly different pressure and high pressure) 

 Choose the Magnehelic ? Dwyer pressure gauge can be obtained within 2% full scale accuracy, and up to 81 species of scale range choice, you can meet your precision application needs. This gauge uses Dwyer simple, no moving parts wear Magnehelic ? can quickly indicates low air or corrosive gases - positive, negative pressure (vacuum) or differential pressure can be. The design impact, shock, and the ability to resist overpressure. It does not manometer fluid to evaporate, freeze, and will not cause toxic or leveling problems. In addition, its price is very low. 
 This gauge is widely used to measure the fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop caused by orifice plates, foam system and fluid level or hydraulic pressure amplifier system pressure. It also checks gas - air ratio controls and automatic valves, and monitoring of pharmacy and respiratory care equipment blood pressure. 
 Installation: Most Magnehelic ? gauge shell color the same size. Can take advantage of the hardware provided with the product installed on the gauge surface or embedded installation. A-610 type with pieces of pipe installation, you can easily install it in the horizontal or vertical 11 / 4 "to 2" pipe. Although it is calibrated for vertical position, but a lot of range greater than 1 ", just a simple re-zeroing can be used for any angle. However, in order to achieve maximum accuracy, they must use the same location with the location calibration. These features make Magnehelic ? gauge both the fixed installation or for portable use, are ideal. If you want to be embedded installation, you must drill a 49/16 "hole. Each device is equipped with complete installation and fittings and instructions. 
 Vent 
 If an application, the pressure is continuous, and easy to move Magnehelic ? gauge metal or plastic tube is connected, we recommend that you use the Dwyer A-310A-pass valve to connect the pressure gauge. This allows you to check the pressure gauge or pressure gauge to remove the zero adjustment.
