76 µm even though this is a very old car that is a good vacuum level to achieve

- When you have the right vacuum pump and lucky enough not to have a severely moisture contaminated system  it’s very easy to achieve a good vacuum 
76 micron at sman 480v , worst case if micron gauge at HP port, suction limited to LP port, i think you still get 220 microns... can u Tom ? Those small yellow jaciet i tried can do 70ish microns, so good for a 1/4 size.
@@suryaprihadi2258 70-ish is inside the manifold directly off the True blue vacuum hose
Yes, it would be well over 200 µm inside the system
And vacuum decay will still go up to 500 or so .
How was your showing the demo and I think hopefully I put in the description describing with the vacuum pump running vacuum open
People always like to take shortcuts and the simplest information and think 70 is good not understanding the vacuum source needs to be turned off and the system allowed to stand and decay
But but anybody who already has purchased a refrigerant manifold with a micron meter knows it’s usually not possible to hit even 100 that fast you have to have a extremely dry system
Your hoses have to be dry
Your hoses are your biggest source of moisture and refrigerant, contamination, absorbed into the rubber surface of the wall of the hoses
I want to know your opinion on whether to buy the Navac NRDD or NRDDF. I see you using your NRDC4M to recover R1234yf, (but is compatible is that ok?) and the NRDD is more affordable right now than the NRDDF I ask you this because I'm about to get one of those I'm just going to use for automotive matters. If you have any other recommendations, I'd be happy to hear it. thank you for reading.
@@saturno4236 nrdd you’re not doing flammable refrigerant.
Unless you are doing flammable, refrigerants, propane or butane
YF it is not a flammable refrigerant. It is barely a flammable refrigerant that is extremely difficult to get to ignite and as soon as you ignite it, if you take away the ignition source, it puts itself out
Do you know where to get a calibration vial for the stratus?

@@coldfinger459sub0 awesome, thank you. Have you ever needed to change the sensor in your stratus?
@@nservice1625 yes after about two years.
@@coldfinger459sub0 I just ordered the r134 reference leak. Do I just hold it up to the bottle or do I just pass the shiffer past the bottle?
@@nservice1625 bottle at room temperature 70°F roughly.
Let it stabilize temperature overnight .
Remove the lid let it sit out a few minutes to air out .
And you should be able to pass the sensor I can’t remember the exact measurement roughly 3/8 of an inch or a quarter of an inch in a slow motion continuously without stopping and it should pick it up
You should NOT have to press it down into the hole and hold it .
I have done some video showing how to do it
And I believe INFICON has made some demonstration videos to .
