1. Main Usage: Digital handheld stroboscope is used to measure the rotational speed or vibration frequency of rotating equipment. You can easily inspect surface defects and quickly identify their positions without physical contact or stopping objects.2. Good Features: LED stroboscope has a longer light range, repeated flashing, providing clear images, accurate positioning, and faster measurement in daily operations. It has ultra low power consumption and can work continuously for 8 hours with a standby time of 3 months.3. Suitable for More Situations: Even without reflective tape, rotational speed can be measured by simply marking or identifying existing markings on the tested equipment, with asymmetric markings being preferred. Perfect solution to the problem of difficult adhesion of reflective tape in high rotation systems.4. Wide Applications: Digital handheld stroboscope is widely used in industries such as gear meshing, , CNC machine tools, papermaking, printing, turbines, drive motors, fans, etc.5. Reliable Performance: Good helper for preventive maintenance, printing inspection, harmonic analysis and repeated speed measurement.Spec:Item Type: Digital Handheld StroboscopeProduct Material: ABSWeight: Approx. 513g / 18.1ozMeasurement Range: 60-999999rpmIlluminance: 1500LXBattery: 2200mAhBattery Model: NoneBattery Type: Lithium Battery (Shipped With Built In Battery)Working Temperature: -10℃ 50℃Display: LCD Display ScreenProduct Size: Approx. 21x8.8cm / 8.3x3.5inHow to Use:Step 1: Power button: Press the power button, turn on the power, and the instrument will work; Press again, shut down, and the instrument saves the last speed dataStep 2: Phase button key: Switch to the phase key (S) and rotate the dial left and right.
