Multifunctional Tester for Transistors for automatic detection of NPN and PNP transistors, N-channel and P-channel MOSFET, diodes, thyristors, resistors, capacitors or other devices. Easy and convenient to operate.
The DSO Shell has a bandwitch similar to the DSO138, although it contains significant improvements in structure, mechanics and operation. The Display and MCU are now mounted on the same board to avoid the use of pin-headers between boards. Feedback from DSO138 users showed that welding on pin heads is often problematic for many beginners.
This Sound Level Meter is a stable, safe and reliable digital sound meter. The entire circuit is designed with the single chip processor as core, using the advanced circuit for sampling and signal processing.
