- Contact Angle Meter, DMe-211.Hotline: 02439942289
The DMe-211 is an economical yet fully-featured contact angle meter with a computer image analysis system.
The unit combines manual droplet volume regulation, and stage up/down motion for gentle deposition of droplets with "FAMAS-basic" software controlled analysis of static and dynamic contact angle (30fps) as well as surface and interfacial tension using the pendant drop method. Analysis software to determine the surface free energy of solids is a standard feature.Features
Automatic recognition of droplet deposition
Live image display and droplet volume monitoring
Movie converter
Manual dispenser with a set of 5 glass syringes and 5 SUS needles for precise adjustment of droplet volume and quick refilling and replacement of liquid samples
Fine adjustable stage in z-axis for gentle deposition of droplets without distortion
Adjustable level of the body and stage
Droplet calibration standard for standard view, bearing one full circle for calibration and three droplet silhouettes of 5º, 60º, and 108º for periodic inspection of measurement accuracyApplications
Determination of wettability of surfaces like glass, metal, plastics, ceramics at ambient temperature
