Product Information: The SMAN3 automatically calculates target superheat, so you don't have to worry about guesswork or manual calculations. WIth the SMAN3 you also get a built-in micron gauge with resolution from 50 to 9,999. On top of that, the SMAN3's exclusive micron alarm allows you to set the alarm to a chosen micron level, and when the vacuum reaches that level, the alarm will sound, freeing you up to keep working when pulling a vacuum.
