Hydrocarbons. I tested it by using the natural gas range top, but not yet
lit. Didn't work. I called TPI customer service, and he walked me through a
couple things, and now it detects hydrocarbons just fine.

My halogen detector is by Tif, whole different sensetivity.

Not sure if they are "certified", but some heatinig and AC supply houses
have gas leak detectors for hydrocarbons. I got a used TPI from Ebay,

works fine. Runs on D cells.

Hydrocarbons, or halogens?
