Crystal Oscillator Frequency Counter Tester - 1Hz-50MHz Range With 5-Digit Display

Electronics hobbyists and repair technicians, this frequency counter is a seriously handy tool to have in your workshop! With a range from 1Hz all the way up to 50MHz, it can test most common crystals and oscillators you'll encounter in electronics projects. The five-digit resolution gives you precise readings, and it can handle crystal testing from about 4MHz to 48MHz (just note it doesn't work with 32.768kHz watch crystals). The compact 80x53mm PCB is packed with functionality, and it can be powered by either USB 5V or an external DC power supply between 5-12V. Now, important note - this comes as a DIY kit, so you'll need to assemble the components yourself if you're comfortable with soldering. The satisfaction of building your own test equipment is pretty rewarding though! Once assembled, it's perfect for testing oscillators in computers, radios, microcontrollers, and various electronic devices. The display is clear and easy to read, making quick work of frequency verification tasks. Whether you're repairing vintage electronics, building new projects, or just learning about oscillators and frequency measurement, this affordable tester delivers professional-grade functionality without the high cost of commercial test equipment. It's one of those tools you didn't know you needed until you have it, then you find yourself using it constantly for troubleshooting and verification. Just be ready for some assembly work, but the end result is definitely worth the effort for anyone serious about electronics.
