Packing List 1 x Digital Strobe Light Tachometer AI-DT100B1 x USB Charging Cable1 x User Manual Zero-out Phase Adjustment Data Storage & Review 360° Rotating Rotary Dial Real-time Stationary Observation Dimmable Strobe Light Brightness x1, x10, x100 Strobe Light Multiples Display RPM & Hz Reading Digital LED Stroboscope AI-DT100B 60~999,999 RPM/Hz, 0.001% High Accuracy, Data Logging & Review AIOMEST AI-DT100B LED Strobe Tachometer features a new LED light source that flashes at a specific frequency. By adjusting this frequency to match or synchronize with the rotation or movement speed of a high-speed object, the object appears to move slowly or remain stationary, even while in motion. This enables the detection of the object's rotational speed, surface quality, or movement condition. Widely used for measuring the rotational speed of motor, fan, pump, and gear machining inspection. Specifications: Measuring range: 60-999999 RPM RPM Measurement Accuracy: 0.001% Luminous Intensity: 1500 Lux Adjustable LED Strobe Light AIMOEST LED strobe light offers illumination with an impressive brightness of 1500 lux, adjustable from 10% to 100%. Unlike traditional laser tachometers, which measure rotational speed using a laser beam, our LED strobe light allows for non-contact observation and analysis of moving objects. The adjustable brightness ensures optimal visibility under various lighting conditions, improving accuracy and ease of use. This flexibility makes it ideal for a wide range of applications, from industrial inspection to lab research. Hand held LED Stroboscope Weighing just 320 grams and measuring 210x90x57mm, this digital stroboscope is perfect for on-the-go professionals. Equipped with a built-in 7.4V/2200mA lithium battery, it boasts a remarkably low power consumption of ≤0.2W during operation. You can rely on it for continuous work up to 8 hours, and an impressive standby time of 3 months, ensuring readiness whenever you need it. USB charging feature, making it easy to recharge from various power sources. 0.001% High Accuracy AI-DT100B is not just an rotatinal speed Tester capable to measure speed 60-999999 RPM/FPM with 0.001% high accuracy, but also display the measurement Frequency Hz reading at the same time. Your reliable FPM speed reader in troubleshooting gear meshing, spinning, HVAC, paper making, printing, turbines, driving motors, engine and fan etc. How to Measure RPM Speed with Strobe Light Stroboscope AI-DT100B?
