    You can buy a cheap leak detector for what the reference bottle costs ya....

    Life is too short to eff with cheap tools.

    Don't know if it's R-11 or not but this is what Bacharach uses for their H-10G.

    Just had a guy give me one of these. Haven't used one since the 70s. Thought I might try to put it back to pristine condidtion. Looks like I'll need a reference vial,,,and a new boot for the probe, and probably the 110 volt adapter for this one. The cigarette lighter adapter is in the box. Who has parts and accesories????
    One way to outthink people is to make them think you think. They'll think you're not really thinking what you're trying to get them to think you think...........

    I know you can get most stuff through Johnstone.

    (at least the branch I deal with has taken care of me.)

    Tru tec tools sells them but they don't list the accessories, but, I would give them a call also (good people to deal with).

    I have used an H-10 for over 25 years. I would estimate that I have refilled that reference bottle 2 or three times. When I see that it is empty, it is sometimes years before I refill it. It is not that critical to have it. It is a convenient way to test the detector, since it is a calibrated leak rate. And I have never heard of R22 being harmful for the H-10. I have used it on R22 many more times than I can recall. Or even estimate. I seem to recall that the pre-R134a versions were not sensitive to HFC refrigerants.

    It may help to think of the "large-medium-small" selector switch as a sensitivity "scale selector" switch. I always kept mine in "small", unless I was in an area where there was such a large leak that the detector was overwhelmed to the point that it would not stop clicking rapidly (more like a loud growl), even with the probe pointed away from the unit. Turning it to "large" would decrease the sensitivity to the point that it could be adjusted to slow the clicking.

    has anyone else refilled their H10g test vials with R11?

    Do not 'calibrate' with any refrigerant!

    The point of the R-11 bottle was to simulate a REALLY TINY leak. If you just use a puff of other refrigerants 'just to see if it's working' it will drastically shorten the life of the sensor.

They supply you with a tiny bottle with a screw and hold in the center of it, but no refrigerant is in it now. You are right to say that this unit requires tons of patience.

    Thanks again!

    when leak testing r22, start at the med switch position. The small position will eat the sensor. Battery models can be a pain...you must charge them. batteries are available for $20.oo but make sure not to cross the polarity.

    Really? Where can I get a battery for $20. ?

    I have a brand-new battery-type H-10 that I have never used. It seemed like a great idea but after getting it I kept using the corded ones while the battery one sat in a closet until the battery failed. <g>

    Speaking of technique: I always start on the LARGE setting to go over the system. If that turns up nothing, or just an intermittent 'trace' response, I then switch down to MEDIUM and retrace my steps. About the only time I ever have to use the LOW setting is for braze joint porosity and eroded u-bends.
