Introduction This machine is suitable for testing various types of connectors, such as insertion force, extraction force, plastic retention force, and service life. Through computer analysis, it can accurately measure the load, stroke, and corresponding change curve of the tested object. It can also accurately control the stroke, speed, target measurement times, and pause time of connector insertion and extraction force testing. Especially with various specialized clamps and fixtures, the connectors can be more automatically centered and aligned during testing, without the problem of "eating one side" occurring. By using the Chinese screen settings in Windows, the operation is simple and convenient, and all data can be stored (such as test conditions, displacement, curve plots, life curve plots, inspection reports, etc.), making it a reliable high-performance testing instrument. Equipped with a dynamic impedance testing system, it can test the insertion and extraction force while also testing the dynamic impedance and drawing (load stroke impedance curve diagram)

Working Principle: The special wavelength of YAG laser can penetrate skin of human body according to the theory and practice of "selective laser decomposing", the instrument uses the laser-wave to break Chromatophore into pieces which can be naturally absorbed by the body. So that it achieves the purpose of de-freckling. The Q-switched Nd:YAG laser radiates the light with a specific wavelength in high peak energy pulse; hence the light penetrates the tissue only for an ultra-short nanosecond. The light is absorbed by the pigment tissue and results in an instantaneous blast, that is Light blasting principle. The pigment particles are shattered into fragments, parts of them will be bounced out of the skin and other parts will be split into tiny particles that can be engulfed by phagocytes and then metabolized by the lymphatic system. The 1064nm wavelength will shatters and removes the black and blue pigments while the 532nm wavelength will shatters and removes red, pink, purple and brown pigments of the tattoo or other pigmentations without damaging the normal tissue Specialty of QM-Q1 New Medical and Elegant design Ergonomic design handle, super long lifespan which can reach 2 millions shots ! 2. 3 Laser tips: 532nm, 1064nm, 1320nm can meet different pigments and black doll treatments Non-pain tips are for option Technical Specifications: Peak Power 500W Wavelength (Spectrum) 1064nm & 532nm (1320nm optional) Energy Density (Fluence) 1-2000mJ Spot Size 2-7mm Pulse Repetition Rate 1-10Hz Pulse Duration
