Contact Angle Meter - DM 211, For Laboratory Industrial, Display Type : Digital

Kyowa Interface, Japan have been manufacturing contact angle meters since 1960.The contact angle meter also goes by the name goniometer. These instruments are used in contact angle measurement, surface free energy analysis, and surface or interfacial tension measurement.

DMe-211 are economical yet fully-featured contact angle meters with computer image analysis system "FAMAS" software enables automatic analysis of contact angle. The upper grade model DMe-211 enables measurements of surface/interfacial tension by pendant drop method as well.

Analysis of surface free energy is possible with optional add-in software.

FEATURES:

• Possesses “Droplet-trans detection” and enables variation over time in 1FPS.(DMe-211 only)
• Stage up/down motion enables gentle deposition of droplet without distorting it.
• Level of body and stage are adjustable. This is significant for measuring hydrophobic surfaces.
• Standard droplet sample is attached for periodic inspection and calibration.
• LED light source is used to eliminate temperature effect to the measurements.

STANDARD COMPONENTS:

• DMe-211 main body
• Dispenser
• Set of 5 glass syringes and 22G SUS needles
• Standard droplet sample (standard view)
• Acrylic plate (for practice)
• Level
• USB cable
• FAMAS software installation disc
• Operation manual (English)
• Laptop PC (Windows in English)*
