Stroboscopes remotely measure the speed of moving machinery. You can measure RPMs from a safe distance and limit your risk. If you want to check the performance of difficult-to-reach equipment, use a stroboscope. Even better, many stroboscopes are able to slow down or freeze reciprocating or rotating machinery so you can visually inspect it. Inspections can save you time and expense by revealing when equipment is operating less efficiently. A stroboscope also can be useful for checking pump operation, propeller performance, gear movements, industrial fan speeds, oil leaks, and more. Tachometers or laser tachometers come in contact, noncontact, and dual-style formats. Those using laser beam detection enable precise RPM measurement. Some include contact adaptors for taking both contact and noncontact measurements. For hard-to-reach measurements or those in difficult areas, use a noncontact tachometer. Tachometers are microprocessor-based with limited memory capabilities. Combination meters (tachometer/stroboscopes) are also available for two-in-one meter features. These units can measure rpm and speed and conduct motion analysis. To harness the advantages of both meters—and expand your application usage—these dual-function models may be your solution. This pocket LED stroboscope is a compact, rugged, lightweight device that provides a super bright, uniform light output for performing visual diagnostic inspection and rpm measurements. The silent cool running LEDs are extremely energy efficient, providing up to five hours of operation on a single charge. Additional features include external input for remote triggering or tachometer mode, pulse output, memory for up to five preset flash rates, and tachometer mode for speed measurements up to 250, 000 rpm using optional remote sensors and TTL pulse output. Whats Included: Universal recharger 115 to 230 VAC, interchangeable wall plugs, NIST-traceable document provided by the manufacturer. Model PLS-Kit also inc.
