Carbon Dioxide Meter Installed at Kartchner

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. CO2MeterComp


Howdy All,

Tonight witnessed the building of a field deployable housing for the carbon dioxide monitor that will be installed at Kartchner Caverns. Here is a picture during construction. I used a leatherman (front-center) to cut holes in the plastic housing (center) for the carbon dioxide monitor (left). I also added a picture hook on the back of the housing so it can be hung on a post (screwdriver front-center-right). After I finished cutting holes in the housing, I covered them with the air filter (back-center-left) and glued the filter to the housing with the loctite glue (right).
