Portable Contact Angle Meter: PCA-11
Fully Automated, On-Site Surface Wettability Analysis
The PCA-11 Portable Contact Angle Meter is a compact, lightweight instrument designed for non-destructive, on-site evaluation of surface wettability. Unlike conventional stationary contact angle systems, the PCA-11 enables accurate contact angle, surface tension, and surface free energy measurements directly at the point of use – on large, fixed, or difficult-to-move samples.
Weighing only 650 g and featuring single-click fully automated operation, the PCA-11 is ideal for manufacturing floors, cleanrooms, field inspections, and quality control environments where rapid, reliable surface analysis is required.
Key features and Benefits
Fully Automated One-Click Measurement
• Single-click operation controls droplet dispensing, image capture, and analysis
• Eliminates manual handling errors
• Ensures high reproducibility independent of operator skill
This automation makes the PCA-11 suitable for routine QC and non-specialist users.

On-Site & Non-Destructive Testing
• Measures surfaces without cutting, sampling, or damaging the product
• Compact, lightweight & USB-powered design
• Can be used directly on large panels, wafers, windshields, walls, and assembled components
• Ideal for in-process inspection and final product verification
This enables real-time decision-making during production and installation.

Integrated Multi-Parameter Surface Analysis
The PCA-11 supports multiple measurement modes in one portable device:
• Contact angle (sessile drop method)
• Surface tension (pendant drop method)
• Surface free energy of solids using established theoretical models
This allows comprehensive surface characterization without additional equipment.

High-Precision Droplet Control
• Automatic droplet dispensing with 0.1 µL resolution
• One prepared syringe can generate up to 500 droplets
• Visible needle tip ensures precise positioning on the target area
This ensures consistent droplet size and placement, even on small or curved surfaces.
