Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If as general thermometers not designed for downhole use
Standard temperature-measuring instruments are Chapter 90, not oilfield specialized.
If for non-oilfield downhole exploration equipment
Other unspecified machines exclude specific oil/gas field wireline tools.
