Gas and Oil Home Heating Furnaces - Electronic leak detector

Hello! I'm new to the forum. I was an A/C tech in S. Florida for several years until I switched to pipefitting, which is now my current trade. Having been out of touch with the HVAC industry for so long, I'm not up to snuff on the latest equipment and tools.
My question is this: Which is the most sensitive and best electronic leak detector at the present time? (I used to rely on the old GE 110volt detector--it was considered to be the most sensitive one years ago) I am wanting to purchase one for my own use and want the best!
Thanks

You can look at Spectronics Corp
Its a Flourescent leak detection and uses a UV/blue lamp in it

use it with a fluorescent dye injestion kit.

Look at Johnstone Supply $300. to $430 list

I appreciate the info about the dye leak detection but I am wanting info on an electronic unit. I heard Yokogawa had a very sensitive unit but having been out of the trade for a few years, I could use some input.

Lots of info at HVAC-Talk (http://hvac-talk.com/vbb/) on trade equipment.

I still like the old standby: GE's H10-B for r-22

I haven't used an electronic one I trust as much or like more than that unit. MIne is probably 15 years old and still works fine. Only ever changed the element once that I can remember. The only pain is needing 110 volts but on the bright side, the batteries are never dead when you need it.

Thaks what I'm talkin bout! That's the very one I cut my teeth on! That baby will sniff out the smallest whiff of a leak. The only problem is they aren't made anymore as far as I can tell.

On the contrary. Sid Harvey has the H10 by TIF Instruments which is 110 vac and they also have the H10 by Johnson Controls which is 12vdc cordless. BIG price difference, but the 110volt model is under $150. My guess is that GE's patent ran out and they quit making it when the competition heated up.

How is your work load in sunny Florida as a pipefitter? Union here in KC is not working much, even plumbers have slowed down. (union side)
I just bid out a small job and awarded to small union shop. Guys were grateful to get 16 to 24 hour of pay this coming week.

I live in SE Georgia now but I have worked all over the country. Last two seasons in New England. This year I have been unemployed fince February. The construction trade has fallen apart in this country since the economy took a dump. I have been on unemployment pay and hoping things will turn around. Lets hope this is so, before it gets the way it was during the
Great Depression!

Like Ken said they still make the H10A halogen leak detector.
TIF makes them in 110 volts and will get HFC-134a also. Try JOHNSTONE SUPPLY if you have one there, list $241.04

Notuboo see your at KC. My hvac shop is at lake of the ozarks there in Mo. Im a tin bender but did lots of pipe work. Retire now down in florida. Dont know what scale is here. But the homes that they dont build up there are all down here now.The tract Im in was 480 homes. They just put in next to me about 1080 of them . Most of the tract setup's here are for 500 to 1000 homes at a time and there are a lotof them .;) ED

H10 or D-tek .. Also Bachrach has a nice one called the Informant II.

You know the old expression: "Now you've given me more information than I needed to know"? LOL, well now I have sensory overload and enough info for my feeble brain to digest for some time to come. However, I'm leaning toward the old GE copies that hopefully will perform in a similar manner. Thanks for all the input guys, it feels like old times sitting around the HVAC parts house talking "shop" with the gang. I'll be dropping in from time to time to browse and perhaps lend a comment or suggestion.

We'd be glad to hear from you. Stick your head in plumbers forum also and say "Hi".

I use a TIF (Brand name) for leak detection on refrigeration. I use ACT (brqand name) for natural / LP gas detector.
