[High Luminance Flash LED]Compared with ordinary tach meters, this intelligent strobe, 1500 Lux LED, matrix structure lamp base with 16 beads, for much farther light range, repetitive flash of lights, provides image, accurate positioning and faster measurement in daily operation. Extra low power consumption supports 8 hours continuous working, 3 months of standby. [Unconditional Promise]This FPM reader is your good helper in motion analysis, preventive maintenance, printing inspection, harmonics analysis, and speed measurement of repetitive motion. Buy it and use it! provides life-time tech support. [Touchless Tach Gauge]-8000B velocimeter is designed for measuring rotational speed or frequency of vibration of rotating equipment. You can easily inspect defect on and quickly identify location, without having physical contact or halting the object. [Reflective Tape Not Essential]-LED stroboscope is suitable for more conditions, for it can measure rotating speed even without reflective tape, just mark or identify existing marks of the equipment under measured, unsymmetrical marks are preferred. Perfectly solve problem that reflective tape hard to stick on high rotating systems. [Wide Usage Speed Meter]LED stroboscope makes fast rotating equipment appear to be slow moving or stationary, which is widely used in industries, gear meshing, , CNC machine, paper making, printing, turbines, driving motors, fans and so on.
