    Maybe I just got a bad one. It seems to eat batteries.

    Could be....I have used mine on about 15 vacs in the last 6 weeks....still on the same battery although I did get the low battery warning yesterday morning. I will change it on Monday. That doesn't seem too bad for a 9 volt
    I need a new signature.....

    IMHO only a HACK would pull a vaccum on a system w/out checking the micron level . That is truely the only way to be 100% sure that you have zero leaks and that the system is contaminent free .

    Again just my opinion

    If you work for me and don't use your micron gauge, you'll be finding a new employer.
    Perhaps you should have read the instructions before calling.

    NOPE !! Positive pressure can and WILL lie to you , a standing micron reading of 500 or less WILL NOT lie to you !!! There is no arguing with that !!!! I have seen it more than once . Oh and for all of you that do not use a micron gauge , when your gauge on your manifold gets to 30"hg your actual micron level can be 5,000+ !!!

    I 'm the only one at the company , that has one.That's why I take longer on repairs and find more tubes not metering or txv failures, due to no vacuum or not long enough vacuums. Nitrogen is used allot but, when you dry a system you have to remove non-condensibles .

    Posative press won't suck in moisture. I'll stick with that. I have yet to find a micron guage that is accurate or does not require a ton of maintenence.

    I don't need a micron gauge I have a pressure switch on my pump that shuts my pump down at a 500 microns.
