QD 700 Large Platform Optical Contact Angle Meter
Contact angle measurement for large-sized, non-cuttable samples
Product Details
The QD700 Large Platform Contact Angle Meter is an automatic liquid-feeding water drop angle measurement instrument. Based on a large moving platform design, it is suitable for non-cuttable large-size samples, capable of measuring up to 21 inches. The sample stage rotates 360°, enabling effortless testing of all sample positions. It is used to analyze surface cleanliness and contact angle values for PCB boards, iPad displays, touchscreens, and similar surfaces. Standard configuration includes automatic liquid feeding, an industrial-grade profilometric lens, an industrial-grade adjustable-brightness monochromatic cold LED light source, and a professional-grade interfacial chemistry analysis system.
