So this digital tachometer is actually way more capable than it looks for the price. It's a non-contact photo tachometer, which means you just point it at a rotating object with the reflective tape applied, and it measures RPM without any physical contact. The range is insane - from 2.5 RPM all the way up to 99,999 RPM, with resolution of 0.1 RPM at lower speeds and 1 RPM at higher speeds. The accuracy is ±(0.05%+1 digit) which is pretty impressive for a handheld unit. It automatically records the maximum, minimum, and last values, which is super handy for diagnostics. The LCD display is clear and easy to read, and it works from 2 to 20 inches away from whatever you're measuring. It uses a standard 9V battery (not included, so grab one separately) and the power consumption is pretty low at about 30mA. I've used similar models for everything from checking motor speeds on workshop equipment to diagnosing car issues - it's surprisingly versatile. The auto-range function means you don't have to mess with settings, it just figures out what you're measuring. The package includes the tachometer itself, a blue carrying bag, three reflective tapes, and an English manual. For mechanics, hobbyists, or anyone working with rotating machinery, this is one of those tools that pays for itself quickly. The build quality feels solid for the price - it's made from ABS plastic so it can handle workshop use without falling apart. Definitely way more affordable than professional-grade tachometers but still gets the job done reliably.
