I don't know if this is any use for touring vans, or even if it's cheap ???

I have seen the ads for it, yes it does seem cheap compared to most gas alarms BUT it does not detect Narcotic gas, ie the type used in europe by baddies who want to rob your Van or Motorhome whilst you are knocked out/asleep in a layby etc.

Could be useful for this country though, peace of mind etc especially if you have kiddies.

Bet it sells out though.

Hi Frank,

The gas detector you discovered will actually detect all flammable gases, but with differing sensitivities for the different compounds.

They work by detecting a change in the resistance of a tiny electrical filament coated in a special catalyst - this converts anything with a Carbon-Hydrogen bond into Carbon Dioxide, Water and heat - and it's the heat that causes the resistance to change.

So they will detect any petroleum hydrocarbon gas, as well as narcotic compounds like Ether - but not compounds like Nitrous Oxide that don't contain C-H

Note: they are a bit power hungry and won't run from smoke detector type batteries.

difficult to work out where to site it as LPG being heavier than air does it need siting on the floor?

I think you may be talking about this one

We bought this one last year - fitting was easy and it does a self test every time you turn the 12V on followed by some beeps which might annoy some, but we find reassuring.

Not had to serve its purpose yet and I hope it never has to.

We mounted it about 3 in from the floor - I think that was the rec for propane and butane.

3 in from the ceiling was the rec for methane if you want to give some one a message.

All from memory.
