convenient and easy to read magnetic thermometer attaches to any metal
surface including single wall pipes and stoves for a quick and easy way
to monitor burn temperatures. In addition to seeing if the stove is
operating at peak efficiency, the gauge will also indicate a low
temperature that could be a result of dangerous creosote or soot buildup
in the fire chamber or chimney. Indicates from 100°F to 800°F (35°C to
430°C). Not designed for double walled pipes.
