FNIRSI Oscilloscope Promo Codes for October 2026

Great value on the signal generator

I was looking for a decent signal generator but didn't want to break the bank. I found the FNIRSI SG-003A here. The price was already good, and I managed to catch it during a sitewide sale, which saved me a little extra. The unit came quickly, and it's doing exactly what I needed it for. For the features it offers at this price, I really feel like I got my money's worth. It's practical and works well, making it a smart buy for anyone on a budget.

Detailed look at my FNIRSI purchase

I recently ordered the FNIRSI DSO-TC3, which is a 3-in-1 oscilloscope, signal generator, and transistor tester. The ordering process on the website was straightforward, I found what I needed quickly and checkout was smooth. It arrived well-packaged within eight days of my order, which was reasonable for international shipping. Upon unboxing, the device felt sturdy and well-built. I spent some time going through the functions. The oscilloscope part works as expected for its class, and the transistor tester is a very handy addition for identifying components. I had a small question about saving waveforms, so I used their online support, and they replied within 24 hours with clear instructions. The firmware was up-to-date, which was a plus. It's a versatile tool for my workbench, offering good value for its features. The display could be a touch brighter in direct light, but it's not a deal-breaker.

Easy to buy, useful tool

I bought the FNIRSI 1C15 handheld oscilloscope last month. It was pretty easy to find on their site, and I just clicked through to order it. Shipping wasn't super fast, but it wasn't terrible either, took about a week and a half. When it got here, I plugged it in and started using it right away. It's a nice little scope for quick checks on circuits, just what I needed for my garage projects. No complaints really, it just works.

Good product, minor shipping delay

I purchased a FNIRSI 1013D handheld digital oscilloscope a few weeks ago. The device itself is quite capable for the price point, and I've found it very useful for hobby electronics. The screen is clear, and the controls are intuitive enough after a little practice. My only minor gripe was the shipping; it took about 10 days to reach me in Arizona, which felt a bit long. Customer service was responsive when I inquired about the tracking, so that was good. Overall, a solid purchase, just allow a bit of extra time for delivery.

Fantastic portable power station!

I absolutely love the FNIRSI portable power station I bought! It's so compact yet powerful. I used it on my last camping trip and it charged all my devices with no problem at all. The build quality feels super solid, and it's really easy to use, even for a beginner like me. I'm already planning to get another one for my car. Definitely recommend it to anyone needing reliable portable power!
