The Fieldpiece SMAN3 Digital Manifold with Microns for Vacuum is like no other digital manifold on the market - it is the only manifold that automatically calculate target superheat, so the user doesn't have to worry about guesswork or manual calculations. Plus the Fieldpiece SMAN3 Digital Manifold with Microns is the only manifold with the ability to perform a linear adjustment of the pressure sensors based on refrigerant type, temperature, and pressure, and it's so easy, the user can do it right in the field.

WIth the Fieldpiece SMAN-3 Digital Manifold with Microns you also get a built-in micron gauge with resolution from 50 to 9,999. On top of that, the Fieldpiece SMAN/3's exclusive micron alarm allows the user to set the alarm to a chosen micron level, and when the vacuum reaches that level, the alarm will sound, freeing the user to keep working when pulling a vacuum.

By combining new technology with an intuitive, easy-to-use interface, the Fieldpiece SMAN3 makes it easy for you to quickly maximize the efficiency of any A/C or refrigeration unit. Built by the HVACR industry's leading innovator, the Fieldpiece SMAN 3 is packed with the features you want.
