TPS-CA-100C Contact Angle Meter

Summary
360° manual rotary design, equipped with automatic injector and automatic contact angle calculation. Humanized design ensures high repeatability and stability of test results. Supporting software is included.

Technical Features
● The whole instrument frame is made of all-metal aluminum alloy, sturdy and durable. Modular structure facilitates disassembly and assembly to meet different precision requirements.
● Threaded adjustable square platform. It can be adjusted freely to keep the droplet platform level even when placed on uneven surfaces.
● Adjustable wide-range camera mounting bracket. Teflon camera protection ring prevents scratches during movement; hex screw locking structure fixes the camera tightly and avoids shaking.
● Ball screw and guide rail design ensures fast and accurate movement of the droplet platform in X and Y directions. Manual movement precision: 0.01 mm. Adjustable travel range up to 80 mm back and forth, for positioning the camera and sample table at the optimal position.
● Adjustable horizontal sample stage for leveling operation.
● Micro-sampler titration with precision of 0.005 μL. Needle locking structure available. Optional stainless steel or PTFE needles for different testing needs. The droplet sampler moves vertically with an adjustable range up to 60 mm.
● Manual 360° rotating platform, rotation accuracy up to 0.01°.
● LED cold backlight with continuously adjustable brightness, showing clear droplet contours. Low heat generation, avoiding droplet evaporation caused by long-time testing.
● High-performance industrial digital camera with high resolution, high definition, good color reproduction and low noise. USB2.0 interface for plug-and-play. Equipped with industrial continuous zoom lens (0.7–4.5×). Standard camera resolution: 2048 × 1536, frame rate: 25 fps. Optional 3MP / 5MP cameras with frame rate up to 100–300 fps.
● Calibration function and standard calibration accessories are provided.
● Built-in video recording function.
● Solid surface free energy can be measured by one-liquid method and two-liquid method.
