The saying “if you spend few amount of money you get shit” is not always valid and this could be an example.

I would just like to clarify before receiving gratuitous insults that these tools are intended for Hobbyist use and NOT Professional.

FNIRSI (Shenzhen FNIRSI Technology Co., Ltd.) is a large Chinese manufacturer of electronics instruments at low price, given the very low cost i wanted to try three products and i was pleasantly surprised by the operation and precision, they are less ‘Chinese’ than other products with the same price.

I wanted to make a simple comparison with the FNIRSI® 2C53T (3in1 Oscilloscope 50MHz, Multimeter, Signal Generator) and with my now ancient WELEC W2022A oscilloscope with some problems and should be replaced, but that said the FNIRSI defends itself well and for some measurements it is more precise, the same goes for the smaller model namely the DSO-153 2-IN-1.

The Smart Digital Tweezer is undoubtedly very comfortable and quite precise, I noticed some hesitation on the measurement of Electrolytic Capacitors even after calibration while it is acceptable for the measurement of Inductors, Resistors and Capacitors (for example Ceramic, Polyester), another strong point is that it is magnetized (see photo) a small adhesive metal plate is provided.

Attention there are different purchase options for these products, some include all the accessories others do not, obviously it costs less.
