Cold testing

I do have a styrofoam cooler of fair size..about 13D x 13H x 23L; adding a fan is no big deal. But that is a lot of moist air. Maybe if i split it with a styrofoam or similar insulating barrier and use Calcium Chloride pellets on one side with a "cooling slot" for dry ice and fan on other side?

VELLY nice! Impressive as well.

Check; did that on the first cut. Was not happy..too much solid water and -15 C was the "best" i could do. At least i could do a rough 6 digit voltage measurement with a 5 digit meter; scatter plots along each V/T line showed the same trend for each measurement set. Yes, crude but a good teaser for better..

From the quickie "specs", seems like the FC770 may be the best choice. Hmmm... Pool of FC770, dunk and fix PCB in pool, splash chunks of CO2 in, keep stirred and do experiment. Might even work in semi-sealed container for all of it. Satisfies the H2O problem. Keeps cost down. VERY worth considering. Thanks.

yeah, XP or newer, Have not looked as 2K, ME, or earlier.

advnced settings under the international settings in the control panel IIRC.

Yes that is what I use, but mine is 7 watt at 70 K IIR. What did you pay?

Yo are so stupid, that you cannot even get a simple colloquialism right.

Sounds like he doesn't know what it does.

Twice? Where?

Not if the Tenny has a dual stage cooling system. Then its just AC line voltage.

Cheers

Maybe partition #1 has the dry ice, hole to #2 with CaCl ten hole to #3 with DUT? I really do not mind dry ice, but the moisture sort-of gets in the way..

• Check; also displaces water to a degree. Was my first thought,but rejected it. Not exactly nice to have if poor ventilation.

• That is back to $$ equipment.

I say "B". I say "B A". I say "B A G G". I say "B A G G Bagg Mopp" .. ((something like that,been a few years)) So updated idea is to use FC77 as working fluid with DUT in (sealed) bag and dry ice outside for temp control - "bag" the water.. Sorry, that means do not care about solid water as it is outside.

Nice! Size? cost? shipping weight and source? Oops - even at free,big prob with solid water.

And lab grade costs. Cannot mess with LN2 dewars or CO2 bottles.

The regeneration is a major plus.

Have lied,setting TZ to AridZona and clock to local (beep) the time now is 8:04PM (beep)

Win2K here..all i see are Date/Time (used for the lie mentioned) and Regional Options which is less useful.

Still set to AZ (-0700) with clock then >> re-done to local..(beep) the time now isn8:16PM (beep)
