Call me old fashioned but give me a little garden spray bottle of soapy water anytime......... preferably the green fairy stuff.... its better for your hands :) and it works with R717 ............

Happy New Year to all you guys.
I have one of those TIF ZX 1 detectors purchased from the States .
They are a fantastic detector and cheap. The only hiccup is the charging unit which is 110 Volts. Easy to get pass with the correct tranny.
I take it back. Mine just stopped working for no apparant reason. If you buy a cheap one off Ebay, it's a fair bet that it is a reconditioned one.
I'm now using a Yellow Jacket Heated Probe unit. Not cheap but it works pretty good.

I have used the Javac tek mate was ok for R22 not much else. I changed to the javac detek its good for R22 but struggles with R404a and R134a the big draw back is the amount of times you have to change the sensors (£40 a time). I now have the javac detek select, the best one yet really good for R404a and you don't need to change the sensors very often. But as with most of the previous comments, you can't beat the old method of pressure testing.
Re Helium - you can use ballon gas grade but you will need a helium leak checker with sniffer attachment to go with it, talking about serious cost US$10 to 15k, also not the most portable. Typically used in factory for manufacture of sealed systems (I used to sell them if you really want to know more zzzzzzzzzz)
I've worked with d-tek and i think it's the best i've ever used also avalable for CO2

We have just discovered the new TIF leak detector and find it to be a cut above the others. The trick is to alter the sensitivity with all electronics, and TIF has a friendly way about it. Sometimes you have to just step outside and reset and go back at it. I can't recall the exact model I am using, but it finds hfc leaks where the detek and others cannot. I also find very useful an ultra-sonic detector. It will pick up the leak often when soap bubbles fail, such as at the lower section of a cap tube.Quote:
I am in the market for a new leak detector and I am not going to part with the cash this time unless I am sure that it will be something good. TIF ZX-1 was one of the brands that I was considering.
Ended up buying a TEK mate again. But next time a leak detector goes down probably will try the TIF ZX-1.
TEK mate is best value for money but has poor sensitivity for HFC's.
Hi Dan
ultra sonic is nice but only in a quit enviorment

Can anyone tell the method to convert annual leak rate ( gm/annum) to rate of Pressure drop (Pa/min) during leak testing of R134a at 10 bar.
Brisbane !!
I found with the tekmate you just need to replace the sensors about once a year or purchase a sensor for the blended gases.
