LS-1004 Automatic Tilt Contact Angle Measuring Instrument

1, Preface

Contact Angle refers to the tangent of gas-liquid interface made at the intersection of gas, рідкі і тверді. This tangent is in the Angle theta between the liquid side and the solid-liquid boundary. Contact Angle measurement is the main method of surface performance detection nowadays.

LS-1004 type the tilting contact Angle measurement instrument is using the principle of optical imaging, image contour analysis way to measure the surface contact Angle, змочуваність, міжфазний натяг столу, поверхнева енергія, rolling slip (Angle), forward backward Angle and hysteresis, наприклад продуктивність, equipment using automatic liquid into the device and the tilting device automatically, fully functional, high cost performance, can meet the demand of conventional measurement, широко використовується в багатьох коледжах і університетах, інститутах і на підприємствах.
