Mercury Barometer
A traditional mercury barometer uses a glass tube filled with mercury to measure atmospheric pressure by the height of the mercury column. Classified under HTS 9025.80.1500 as a non-combined barometer, it's used in laboratories and educational settings despite modern safety concerns.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used for aircraft altimetry
Barometers specifically designed for aviation instruments fall under aircraft instrument classifications.
If for industrial process control
Pressure gauges for compressors or engines are classified as parts of those machines, not general barometers.
If it's a recording barometer
Barometers with automatic recording mechanisms are excluded from the non-recording subheading.
