Digicool 1600 or AK900

Maybe If it wasn't a crappy micron gauge

[Just In Time]

i thought it was the same sensor they used on the 69075?

LOL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The last time I checked they were different part numbers and different % accuracy

The one was 10% and the other was 20%

Depending on your ambient conditions you would probably be better of using the .5% low side gauge on the Digi-Cool while evacuating

[supertek65]

20%!!!!!!!!
that is some percision stuff right there brother!!!!!!!!!!!

when I put the bearings back in a chiller, I like to get the thrust and run out to about 20%! or so give or take??????

[itsiceman]

Well I checked the Y/J site again and one for the Digital Display Manifold Gauge says 20% of reading and
the Super Evac LCD now says +/- 20%

[supertek65]

does the accuracy change at different temperatures??????????????

That's how a micron gauge works.....the rate at which 'the medium' allows the heat to be removed from the element is dependent on the number of gas molecules transporting that heat away by vibrating molecular motion....if it's in a HOT atmosphere.....you're screwed...for accuracy......
Geeeze....20% accuracy.......wow....didn't they go all out...?

[Just In Time]

Doug, are u recommending the BluVac?

[supertek65]

If the micron gauge was a MLB hitter it would be better than Willie Mays!!!!!!!!!!

It's a helluva looking product and I have one on the way.....only one regret ..... that I didn't build it but they are a very principled group and 'get it' as to what we techs need......the decay rate and bargraph is gorgeous AND really innovative engineering.....
I'll let you know but MITTS on the other site sent me review today and said it's SOOOOOO sensitive you can see every 'sweep' of the vacuum pump !!!!

Here's his email to me "FWIW the Micron Gauge ROCKS It reads so fast its like you are reading pressure directly. I was watching the vanes turn in my cold pump Whoa!!! Very stable reading when I changed temperature on the sensor also. Impressive design from AccuTools IMO"

That's the first time I've heard of Bluvac. Looks good.

Interesting calibration procedure.

Hmmm, maybe I need one...... Since the calibration procedure on my Thermal analog now involves tapping on it to get the needle to dial in

I was going to tell ctcont to send that thing to Marvin in Vegas to do his drop test and 'bucket test'. A guy Marvin was touting the benefits of one of our units to, said 'yah, but what about durability and rain'......Soooooo Marvin grabbed one of our units, dropped it into a bucket of water, left for 2.5 hours and came back to get it.....fired it up and has been using it ever since.
Even Jim Bergmann who was the tech support guy for Testo for years said 'Doug, yours is a really effective field tool, the Testo is a lab instrument'....

the drop test was only from 18 ft. &about 6 ft. out into the dirt test so that may not count. on the bucket test we used shipping tape over the obvious
openings on the back side of the 1250 & only because i dont know where
those openings go. also left the sensors connected after checking to make
sure the connector was secure.
have to take them back to weights & measures again to re certify accuracy tuesday & have no doubt that they will fo thru as easy as before.
for a special job for a real pia account.

micron gauge???????

I use Vacinol and a wet bulb indicator!!!!!!!!!!!!!!

[marvin]

i ordered the blu vac last week & should see it tomarrow or tuesday.
im also looking at their combustable gas detector.
very interesting web page & product line.

[supertek65]

Marvin
let us know how you like it!

The second point is that 'engineers' (and I use that word VERY loosely) are the guys that put those into the FP (Fisher Price) and the other one from da Fodderland.....THEY DON'T WORK IN THE FIELD......!!!!

Now that is funny!

[Doug Lockhart]

Mitts has a quick video on the Blue Vac..

Let me know what you think doug.

Boy tools like this that make me miss being out there.

[Vettgetsmwet04]

i like that micron gauge, thats goin on my summer list
