SDP-300 portable contact angle tester Introduction
Portable contact angle measuring instrument, mainly used for large-scale sample measurement, or contact angle measurement of a special sample, or where it is necessary to frequently change the measurement location. For example, computer screens, TV screens, larger sized glass, automotive housings, etc., conventional contact angle measuring instruments cannot meet the requirements. Portable contact angle measuring instruments have been applied to measurement research or quality inspection of materials, automobiles, circuit boards, touch screens, televisions, etc. due to their light weight. It can be perfectly matched to the full-time automatic detection of the production line. Features
Light source system:
The uniquely designed LED light source has a service life of more than 20,000 hours and an extremely low heat dissipation, which significantly reduces the effect of heat on the volume volatilization of the liquid. The leading light guide design and materials ensure that the light is evenly parallel and the image is sharp and clear.
Optical system:
The high-fidelity telecentric lens avoids the imaging distortion produced by the ordinary lens of the rabbit, ensuring accurate measurement of the contact angle measurement over various angular ranges.
Camera system:
1.3 million black and white pixel industrial grade camera, high-speed acquisition of 30 images per second, USB2.0/3.0 data transmission, providing excellent image quality.
Injection system:
The optimized design of the injection system, with an accuracy of 0.1u1, allows quick replacement of liquid samples for surface energy testing. Single tube liquid can be continuously measured more than 200 times. A single test time is less than 2s.
Analyzing Software:
The domestic leading analysis algorithm, differential circle method and differential ellipse method not only accurately fit the data, but also accurately measure the left and right contact angles and the forward and backward angles. Powerful analysis algorithms for sample measurement in a variety of routine and special applications.
Convenient operation:
Quickly measure, get data quickly, and export comprehensive data results reports. There is no need to adjust the power every time, no need for human analysis adjustment. All measurement operations can be performed with one hand, which is suitable for quick and convenient industrial quality inspection.
