Description

Technical Field

[0001] The utility model relates to the field of graphite furnace inspection and cleaning, in particular to a multi-purpose graphite furnace inspection tool. Background Art

[0002] Since the inside of the graphite furnace is not easy to observe, when the graphite tube is damaged, the carbon slag is not cleaned properly, causing the new graphite tube to short-circuit during use, thereby damaging the graphite tube. In severe cases, the graphite cone will be damaged, causing the graphite tube and atomic absorption instrument to require frequent maintenance.

[0003] The lighting mechanism of the graphite furnace inspection and cleaning tools is mostly fixedly connected to one side of the detection mirror and cannot be adjusted at a lateral angle. This results in that some angles inside the graphite furnace body cannot be clearly observed, affecting the cleaning of the inside of the graphite furnace body. Utility Model Content
