Frequency counter and crystal tester kit: 1 Hz - 50 MHz
Not always the case, but here’s a video of unpacking and assembly that’s nice and easy. No fiddly SMD soldering. Everything is shown with the rhythm of an electronicist who gets his kicks with good old fashioned through-hole components. This kit is a dual-purpose pocket test equipment, an affordable frequency counter (1 Hz à 50 MHz) and crystal tester. It has five standard 7-segment displays. Look at the measuring range: 1 Hz to 50 MHz. Especially for this price!
