FNIRSI-138 PRO Oscilloscope

The FNIRSI-138 PRO Oscilloscope is a very useful tool for beginners and hobbyists in electronics. It is compact, lightweight, and easy to carry, which makes it suitable for quick testing and basic troubleshooting. The display is clear and easy to read, allowing users to view waveforms without much difficulty. Basic functions such as voltage measurement and signal visualization work well for simple applications. However, if you plan to use it for field work, you may need to make an enclosure to make it more sturdy and to add extra protection to its circuitry. Overall, it is a practical and affordable oscilloscope for learning and basic use.
