Thermometers for smokers

[AAlmeter]

I've got this http://www.chargriller.com/store/pro...396f7057e136ab

without any mods. So to keep an eye on temp I used something like this

A couple hours into my ribs, the thermometer crapped out on me. Any suggestions? I typically rest the probe near the meat so I get an idea of the ambient air temp in there? I am doing it rightly/wrongly?

Thanks
