Is there a kit that will test for all brands of inhibitor?

Not heard of one that does all brands - there is I believe a kit that tests the wuality of teh water in general though.
Fernox do their own as does the Sentinal maker (buggered if I cam typing the full name though  ).

Looka t the Feature on the Gas-news.org site - it's dicudded there.
Ho gwad Dan I'm triping just lik u..

Another test which can give a suggestion is to mesure the conductivity of the sytem water.
A proper conductivity meter is quite costly but i ue my test meter,immersing the probes a consistent amount and spacing to give me a comparative result. I do it first in tap water then the system water.
This will tell me if there is NO inhibitor i.e. high resistance. If its a low resistance then there MAY be inhibitor in it or there may be flux or other comtaminates. Therefore this test is useful to me but not conclusive.

Could you send me some more info on that test please? I assume you mean a standard multimeter?
CHeers is advance.

Could be an interesting experiment. Mount two probes a given distance apart, measure resistance with plain water and then with various censentrations of inhibitor added. May not be accurate but it would probably give an indication of relative strength. Might well give it a go.

Once one understood the physics behind it, I can see it being a better "quick" test than many other techniques.
We look forward to a full tutorial Tony .... By the way - did you put something similar on the gas news site?

I was intrigued by this idea so thought id do an experiment by testing the resistance from the mains at kitchen tap and cold storage at bathroom wash basin.
On the mains i got resistance of approx 0.63
On the cold storage resistance was 0.35
So could this suggest corrosion / flux / foreign matter in the cold storage tank / supply pipes?
What do you all think?
Cheers

I have a fernox unit that is battery powered with 2 probes on, it tells you how many parts per million of iron is in the system.
I bargined for it with a fernox rep, suposidly there top secret shhhhh
there blue by the way.
and i shove it in the outlet flow of the flush when im cleaning a system.
It does show higher when chemicals are present

The meter you have will be a conductivity meter that Fernox produce in various guises. Fernox claim that these can be used to measure various things from iron to the level of chemical but in reality the only thing they will measure is conductivity and this is only useful when flushing a system and trying to establish whether the flush has removed all of the cleaning chemical and other deposits by comparing with the mains water.
I get asked the question about whether there is a single test for all inhibitors by councils and housing associations all the time and I can tell you having questioned the manufacturers that the answer is a resounding NO.
Its only worth checking the inhibitor level if you already know whats in the system. Otherwise you need to flush and start again as not all inhibitors are compatible. Some contain nitrite and others contain amines meaning that it is possible to mix brands and end up with a cocktail which is a carcinogen!. Not something that many are aware of but that is unfortunately true! Some of the councils I work for now only use inhibitors that dont contain either nitrites or amines because of this and this is an approach that is growing. You would be surprised which brands contain one of these two elements! |
