Want to keep an eye on rotating parts? Track the spin speed of your industrial equipment with this tachometer from SKF. It monitors your machine's crankshaft to give a precise picture of its angular velocity for easy maintenance. The backlit colour screen displays your readouts so you can take appropriate action, while the user-friendly button-operated control allows for fast configuration. Thanks to dimensions of 295 (L) x 70 (W) x 38mm (D) and a 270g weight, the tachometer fits neatly into your palm for one-hand operation. This multitasker not only takes optical and contact measurements but also linear and rotational speeds, with distances thrown in for good measure.
