    Digi Cool & Tank Sat.

    Did a experiment with R 22 Satutaion And the Digcool verse Analog

    Test a sample(s) of r22 with know levels of moisture added.

    With the Digicool it was easy to spot with a sat test even at very small amounts.

    Anolog had to have higher levels to spot.

    Can you explain this test?

    I'm looking for a way to justify digicools to the boss (wife ) and if they can do something that would help me more accurately than what I currently use, then I have a way.

    I made a test set up out of 1” copper 3” long Both sides crimped and brazed with Schrader on both ends Then I pressure tested them for about 1 week at 175 PSIG maybe longer I don’t remember . (x6)
    Pull it to 150 microns standing vacuum test for a day. Did this for all for all 5
    Took one and Filled (80 %) it with R22 sorry can’t remember the weight need to look it up on a pipe Chart. Did this amount for all Six
    Chamber 1 Filled with R22 from a vacuum standing vacuum (24 hr ) of 150 microns let stand for 12hr 24 hrs at 70 deg F Stat out on the Nose 48hr.

    Chamber 2 Let is stand open to Atmosphere for 20 min then filled with R22 at 70 deg F stand for 24hrs 48hr 72 hrs reading.

    Repeated this above only change
    Chamber 3 Let stand to Atmosphere for 2 hrs
    Chamber 4 to Atmosphere for 24 hr
    Chamber 5 open from a vacuum of 150 micron in shower with room air 100% RH left open for 20 min
    Chamber 6 added 5 drops of water from Eye Dropper .
    Digicool show changes on all of them.
    Analog and Fluke 52-2 with pipe clamp Possible Moisture on 4 and moisture on 5 and 6.
    Sorry I Did this near the end June of 2008 and had the numbers wrote down then in July early July The cancer Surgeries’ X3 stared so I never post the stuff. God only know were the paper with the Numbers are.
    A friend brought up he Sat a tank and I decide to post. If When I find the number I’ll post them.
    Or my son and I might do the experiment again when I feel better.
    I (we) made the Chambers so we could learn about Temp/Pressure Relationship. Vacuum and micron ect…
    I Hope this helps.

    Hi

    Please help me here im not understanding how you are able to determine moisture on the analog or the digital. What do you look for?
    Analog and pipe clamp? Im totally lost at what the pipe clamp is doing... temperature??

    Thanks
