Are you talking about a leak detector (for unburned LPG gas) or a detector for carbon monoxide?

The Mitre 10 Quell CO detector ($49) seems a lot cheaper than the ones offered in various RV accessory shops:

But it has a CE EN50291 certification mark on it so it should be fine:

I run a combined CO/Smoke detector (ex Mitre 10 but I don't think they stock them anymore), and an LPG alarm. The all cover different things - smoke from fires, CO from faulty appliances and LPG from a leaking appliance or gas line. Covering off all three in the confined space of a motor home is worth while. The one you reference should be a good CO alarm and $50 is as reasonable price as you will get from a NZ retailer.

CO detectors can run off batteries and are very similar on look and construction to smoke alarms. You can still get them for under $NZ10 . The same alarms are on TM for under $15.

LPG detectors need around 50-100mA, so need to be connected to the main house battery. Available on EBay for around $10. . I use one that is available on TM for about $50.

Difference between these cheap models and the one from Mitre10 at five times the price, or the ones from RV suppliers at 10 to 20 times the price - I have no idea... is it the 'NZ Price premium/ripoff' , or is it quality, or is it a bit of both?

I'd go for the middle ground. The Quell detector is certified to a European standard which specifies when the detector will alarm. Who knows when the ten dollar job will trigger? How much is your life worth?

Another thing to consider is the lifetime of the sensor. The lifetime of the belt clip CO alarms used in industry is only a year so I guess these would have a similar lifetime.

If you are caravanning or motorhoming you should have all 3 alarms..
Gas, fire, and carbon monoxide..

Gas about 250 to 350mm off the floor
Fire\smoke on the ceiling
Carbon monoxide at about head high, is my understanding.

One alarm does not cover them all.
Don't go cheap as failure is not an opinion... It may take your life with it.
It should be compulsory really.
Gas leaks are your biggest enemy, it goes with a boom!!!!! :shock:
