don't know a lot about this stuff but?
how accurate is the micron gauge in that range?????????
and then how accurate is suction gauge on a 410a system????????????
or the high side of a 410a system??????????????
what I am getting at is the range of the sensor????????

Anyone who is a true Reefer Tech knows that vacuum operates on a different (molecular) level than pressure and the micron gauge MUST go as far from the vacuum pump as possible to read accurately/properly. I wanted as well to do this (as I am in coveralls and packing all the same 600# of 'stuff') but I have proven many times....it's about useless to have the micron gauge in the manifold.....not to mention the 'failure' of the sensor trashing the whole manifold then!!!!
Don't believe me.....try installing a micron vacuum guage at those two different points and call me with your results. 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......!!!!"The quality you deserve is not expensive---it's priceless"

the stuff I work on, I place the micron gauge far away from the pump.
On large splits I usually can place the micron gauge in the fan room and the pump outside at the unit, on chillers I can place the vacuum pump on the chiller barrel and the micron gauge on the condenser or at the purge pump.
If I personally ever put in some little unit I always place a service port inside as well as that is where I install the drier to improve the efficiency of the molecular sieves.
I think most residential guys only have the service ports at the condensing unit?
I GUESS?????????? a guy would place the micron gauge on a tee at the service valves?
I have never thought of having one on my manifold????????????????????????????????

I have friends that use the for mentioned TESTO 550.
They seem to have a slight issue with the hook?
I have also heard they do not do well outside?

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 quality you deserve is not expensive---it's priceless"

And thats why i own 2 digi cools......... and i cant wait for the the ak.......
That bieng said, i would NEVER buy the new yj gauges but.... the Micron gauge is remote from the manifold and it plugs in via a yj sensor wire? correct me if im wrong.... but, that could be an alternative that might make some people happy

Maybe If it wasn't a crappy micron gaugeIf You Can Dodge A Wrench You Can Dodge A Ball

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

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??????
