“Testing transistors requires high precision”

No matter how you measure discrete transistors, the accuracy is not very high. First, the parameters of transistors are greatly affected by the environment. For example, temperature changes have a great impact on the parameters. Second, the dispersion of transistor parameters is very large. Even the current amplification factor of the tubes in the same batch may differ by twice.

It would be best if you list the test items and accuracy requirements in detail, otherwise even the instrument manufacturer will find it difficult to recommend.

The transistor test mainly focuses on the β value, and other parameters are determined when the model is selected. For pairing, a graphical instrument is selected.

Please clearly state the test parameters and required accuracy, otherwise the question is meaningless.
