    Not starting out well, just doesn't seem consistent. Also if I bump the tip it beeps and shows 10-15 ppm. Doesn't inspire confidence.

    Tomorrow or Monday I am going to do some leak repairs on a rack and one of them I know about is fairly small so I'll do some real world testing.

    And no, it does not detect anything from the Bacharach reference bottle sitting in my van at 100 degrees lol
    Well, it is a Lennox A-coil, hmmm

    Actually I don't know for sure what kind it is. The original a/c was Amana and I changed it out with a used Lennox. Never did change the 1995 evap. But it had a 2012 goodman furnace

    Haha. I did the same at my place. I replaced the 2008 Goodman furnace but the 1988 Carrier A-coil remains.

    If you do get some results with either detector could you please get a pic or video of the leaks your finding with bubbles so we got an idea what the size is like?

    Will be funny if your AC is leaking. Sounds like it's in the condenser lol

    From what chuck told me last night, it will go off if you turn it on it’s side.

    Just checked my H10 Pro it doesn't alarm on its side and it detects the R11 and it's 81% humid AF

    I bought one of these a couple of years ago...

    Leak Reference

    It's an orifice based leak reference similar to what detector manufacturers use to test/spec their products. I also recently bought a 410A calibration gas with a 10 PPM concentration in an attempt to determine just how well Stratus will or won't detect...

    Using the calibration gas, the highest PPM value indicated by Stratus was 2-3 PPM.

    Using the leak reference as the sample source and holding the probe stationary at the reference discharge, the Stratus consistently detects 410A. The two previous IR detectors I had never consistently detected 410A. That "consistency" is so far the primary aspect of the Stratus that impresses me.

    Based on the calibration gas tests, I've decided the PPM mode reading is a valid indicator of changes in concentration but not necessarily an accurate measurement ​of the actual PPM concentration. But even with that conclusion, I'm impressed the Stratus will detect 10 PPM...in "Pinpoint" mode and "Super" sensitivity setting, the detection level maxes out. The ZX would not detect at any level.

    To my knowledge, Inficon hasn't spec'd a minimum PPM detection value. I'm guessing they integrated that function into the Stratus design to do what it consistently does, which is indicate changes in refrigerant concentration.

    I don't know what you are talking about!!!I have a New Status.It has been good.I turned it on outside today, after warmup, it was quiet as a mouse.It has always been this way.when it gets near a small leak, it goes off ,as expected.I'm not an H10 fan!!!Never had good luck with them, and I have two of them!!! My H10 is older, about 5 years old.It was never as good as the stratus.if a new H10 is that much better than one 5 years old, maybe it is better than the Stratus.For now I will be using the Stratus.I was thinking about getting a new H10.Just to compare the two-but I'm happy with the Stratus.Don't want to really drop the $500.00 now for the H10.So it will be stratus for now.I'm happy with it.

    Does yours go nuts just by tipping it?

    Let me know if this video link works.

    No,Mine seems fine.I think you should call Inficon on that leak detector.Maybe you got a bad one.They are new and yours maybe isn't working properly.If mine did that,I would be pissed!!!!I say call Inficon .

    That's interesting. I seldom see 410a but would that be any different than other 400 series gases? Mostly refrigeration so 407 448 etc.

    The pgm-ir works fine, you have to set the type of gas so it will read ppm more accurately. A Bacharach tech told me that if it is set for a different refrigerant the ppm might not be totally accurate but will still be close. So Inficon must use an average.

    I think too that I probably got a defective one but wanted to try it out in the real world before I call them, just so happens we got slammed with calls today and I wasn't able to go play with any leaking rack systems. No leaks today, but early next week I have some stuff.

    Maybe the sensor cartridge is loose. Could the funky battery door have something to do with it?

    Yeah, that instability isn't normal...

    Since most of the 400's contain a common refrigerant like 125 or 134, you'd think it would detect all of 'em...but to be honest, who knows? I tested 407C and 421A with the reference and it barely detected those. But, they're at a considerably lower pressure for a given temp than 410A so the reference doesn't deliver as much sample.

    I realize the manufacturers have to publish some per annum sensitivity spec and the smaller it is, the better the detector. But we all know there are times when a system is leaking far more than the spec and you can't find it. All I've been doing so far is attempting to determine if the Stratus is way better than the ZX...and for the moment it appears to have a slight edge with 410A. And a consistent slight edge may well make it a winner with me.

    But specs, references and calibration gases are one thing. Finding leaks in the field will be the acid test...
