Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily psychrometric recording
Specific provision for recording psychrometers takes precedence over combination instruments.
If plastic housing dominates without sensors
Chapter exclusions send non-technical plastic articles to chapter 39.
If sensor circuitry emphasized
Electrical machines for specific functions may classify under chapter 85 if not measurement-focused.
