Mining | An instrument giving a continuous record of the methane concentration in mine air. It uses a small flame burning butane in a gauze-protected enclosure. Instead of observing the cap, thermocouples are used to show the increased temperature above the flame, and the resulting signal is displayed on a recording milliammeter. The instrument runs for at least a week and is accurate to about 0.05% methane.See also:methane tester type S. (references) |
