Howdy Everyone,
We successfully installed the carbon dioxide meter at Kartchner Caverns yesterday. Dr. Sarah Truebe has skills with zip ties. In A) we have already linked together several zip ties, tied them around a post outside of the entrance to Katchner and hung the meter on it. Dr. Truebe is preparing another linked zip tie to go around the meter. B) A successfully installed meter and two smiling scientists.
