Digi-Sense 20250-26 Digital Contact/Photo Tachometer, 50 cm Measuring Distance, ±0.05% RPM Accuracy, 0.2 to 6561 ft/min, NIST Traceable Calibration

The Digi-Sense 20250-26 digital contact/photo tachometer is designed for quick and accurate RPM and surface speed measurements on fans, motors, turbines, gears, conveyors, rollers, shafts and cams, spindles, and more. This essential instrument in predictive and preventive maintenance programs lets you identify potential issues early, reducing costly downtime and repairs and keeping your equipment running smoothly.|Easily configure the 2025026 for either contact or non-contact measurements depending on your application requirements. Use the included adapters in contact mode for quickly taking measurements; take measurements from a distance when in photo mode for use on dangerous running equipment.|Features of the 20250-26 include max, min, and values stored, auto-ranging, built-in memory recall of up to twenty last average measurements, and a rugged, lightweight ABS plastic design that fits comfortably in your hand for extended use. Plus the NIST-traceable pre-calibration means you get reliable measurements right out of the box, saving you time and money!
