The Dwyer Instruments A-432 Magnehelic Gauges Portable Kit is a handy and indispensable product used for measuring low differential air pressures in HVAC systems. Based on the Magnehelic concept, this kit is non-powered which makes it convenient for portability. It effectively measures positive, negative, or differential pressures with no friction and wear and with improved sensitivity due to the magnetic linkage system. These could serve purposes of ascertaining filter dirtiness, airspeed in ducts, and different fan indications which are key for better working HVAC systems. Advantages of this portable kit include that it is light easy to operate, and has high shock and vibration resistance.
