Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If plastic integrating sphere component only
Plastic articles of general use classify by material if not apparatus parts.
If non-optical measuring instruments
Measurement without optical radiations (e.g., electrical power meters) shifts headings.
If portable lamps with built-in testers
Lamps incorporating basic indicators classify as lighting, not analysis instruments.
