Portable contact angle measuring instrument

SI-CAM2000P portable contact angle measuring instrument adopts lightweight portable design, can be placed directly on the sample for measurement , therefore no sample size limitations, especially for large area of the sample applications such as the detection of the TFT-LCD. Mainly used to measure liquid contact angle (cleanliness) large glass surfaces, namely liquid to solid wet ability can also measure the contact angle of the liquid external phase. The instrument can measure a variety of liquid contact angle of various materials, such as bulk materials, fiber materials, textile material, powder samples after making into the tablet can also be measured. At the same time this series of instruments can measure and calculate the surface / interfacial tension, CMC, the shape of the droplet size, surface free energy.

Features
1, the use of multimedia computer technology, optics and CCD camera combine to make an image of the droplet clearly displayed on the computer screen, the image is stored in an instant for the next measurement, to avoid measurement failure due to liquid evaporation.
2, It has instantly freeze, automatic continuous photography, high-speed photography three kinds of screen shot way, even the volatile liquid can also ensure accurate measurement. Meanwhile, outside tangent is the biggest problem for subjective factors affect, SI-CAM2000 series contact angle measurement makes the geometric operations being done in software, the contact angle is no longer human judgment.
3, This handheld portable products, no need cutting the product and no need a separate sample stage, no sample size limitations.

Supporting computer:
SI-CAM2000P portable contact angle measuring instrument must combine with a computer. If you choose matching computer provided by the supplier , you need to pay extra 4,000 yuan / set to the supplier, the original brand computer three-year home warranty. If users buy computer themselves or use the original one, the requirements are as follows: WinXP operating systems or 32-bit Win7 operating system, a USB port, an empty COM port (RS232 serial port).
