Is there any way to tell which inhibitor has been used? I have heard if you
mix different types, it may actually make a corrosive mixture.

Or, indeed, is there a way to measure the *strength* of the inhibitor - to
determine whether it needs topping up or renewing?

I know there are testing kits available (A similar thread has a link to a
fernox kit), but you still need to know the inhibitor that was used to buy
the correct kit.

An in my thread earlier (for X100), the X100 tester kit was over £8 + VAT,
and I can get X100 for around £12 or so. Seems almost better sense to just
put in more X100 rather than test.

X100 seems to be about £12 per litre. Is a litre enough for most systems?

Its okay for an 'average' house - which ours is (3 bed semi with around 9
radiators). I think they quote a system volume and estimate of how many
rads that equates to.

One reported way (not tried by me) is to drain a little out and
put a clean nail in it. If it forms a rust layer in a few days,
then the inhibitor is too weak. I assume this would need to be
done in a sealed container or it will absorb oxygen from the air
and use up the inhibitor that way anyway.
