MEASURING (counting Fulltext... Hierarchy... Expanded...G06M); TESTING

|  | G01W |
METEOROLOGY (influencing weather conditions Fulltext... Hierarchy... Expanded...A01G 15/00; dispersing fog Fulltext... Hierarchy... Expanded...E01H 13/00; instruments for measuring single variables in general, see the appropriate sub-class of class Fulltext... Hierarchy... Expanded...G01, e.g. Fulltext... Hierarchy... Expanded...G01K, Fulltext... Hierarchy... Expanded...G01L; obtaining meteorological information by radar Fulltext... Hierarchy... Expanded...G01S 9/60)

|  | G01W |
Note(s) Attention is drawn to the notes immediately following the class title (Fulltext... Hierarchy... Expanded...G01). In this sub-class, the term "meteorology" includes measurement of certain ambient atmospheric conditions.

|  | G01W 1/00 |
Meteorology

|  | G01W 1/02 |
· | Instruments for indicating weather conditions by measuring two or more variables, e.g. humidity, pressure, temperature, cloud cover, wind speed (Fulltext... Hierarchy... Expanded...G01W 1/10 takes precedence)
