Overview
The non-contact laser vibrometer $r $nQC3211 is composed of a laser sensor, a PC, and analysis software. The laser head uses infrared laser that is safe for human eyes as the test light, and measures vibration using the Doppler principle. It can simultaneously measure the speed, acceleration, and displacement of vibration, and can also perform frequency spectrum analysis and waveform recording. Suitable industries include environmental vibration monitoring, rail transit vibration monitoring, electro acoustic device vibration detection, mechanical equipment vibration testing, home appliance factory inspection, fault diagnosis, and abnormal noise detection
