Extech 461830 Digital StroboTach Tachometer - 100-10,000 RPM/FPM Stroboscope, 4-Digit LED Display, ±0.05% Accuracy, Freeze-Motion, Tripod Mountable, 115 V AC

The Extech 461830 is a digital StroboTach tachometer. Freeze motion and analyze rotating objects without contact. Checks and analyzes motion and speed by simply aiming and synchronizing its flash rate (FPM) with a rotating object. Ideal for measuring the speed of moving gears, fans, pumps, motors and other equipment used in general maintenance, production, quality control, or laboratories. Complete with 6 ft power cord, handle and can be tripod mounted.

• Freeze-Motion Non-Contact Speed Measurement - Synchronize the flash rate (FPM) with rotating parts for accurate RPM readings without physical contact. Perfect for gears, fans, pumps, and motors in maintenance, QC, or labs.
• Wide Range & Exceptional Accuracy - Measures from 100 to 10,000 RPM/FPM with ±(0.05 % of reading +1 digit) accuracy, thanks to microcomputer LSI circuit and crystal-controlled time-base.
• Clear 4-Digit LED Display - Easy-to-read readings on a durable, 4-digit LED panel with automatic range indicator for measurements above 10,000 RPM.
• Portable with Tripod Capability - Includes a sturdy handle and compatibility with tripod mounting for stationary setups—ideal for workshop or lab environments.
• Reliable Build & Practical Usage - Compact (8.3″ × 4.8″ × 4.8″), lightweight (2.2 lb) design with a 6 ft power cord. Duty cycle: 5-30 min depending on RPM, with a 1-second sampling time. 1-year (or 2-year per FLIR) warranty included.
