I've been meaning to get a new sensor for my Oxycheq CO analyzer for a while. Was thinking I might go to Marianna this last weekend, and when I never did work that out, I finally called Cave Adventurers. They're out, and Oxycheq is out too! I am going to the Dominican Republic next week, and can't find a new sensor.

Does anyone know of a shop/site that would have one and ship fast? These things are weirdly hard to find.

Thanks.
