Description
The depth of charring of wood is one indicator as to how long the substance burned, how intense the fire was and may indicate the possibility that accelerants were used when charring is exceptionally deep in isolated areas. The gauge permits rapid, accurate measurement throughout the fire scene and often eliminates having to cut out timbers unnecessarily. It is calibrated in 1/64" increments and measures up to 1" of char depth. It is a necessary aid to any arson investigation kit.
