DMo Series
DM0-Series
Contact Angle Meter
The four models of the DMo series are high-performance contact angle meters, only differing in their grade of automation. The high-speed camera and computer-controlled dispenser allow for precise measurements of static and dynamic contact angles, surface and interfacial tension of liquids, as well as analysis of surface free energy of solids. A wide range of options are available and lower grade models can also be upgraded later.
Each model combines the following features
- Fast image capturing system with standard 400 fps at 640×480 resolution USB3.0 CMOS camera, max. 1000fps at 640×200 resolution
- Automatic single dispenser system
- 150x150mm wide sample stage with a maximum load capacity (temperature chamber + sample) of 1.4kgs
- Stage travel distance: x-axis: 150mm, y-axis: 75mm, z-axis: fixed
- Focusing aid with displayed index graph and value and brightness adjustment to achieve perfect focus
- Movie converter to convert data images to MPEG-1 or AVI movie format
- Determination of contact angles, droplet volume, residual droplet volume, sessile drop volume, height and radius of sessile drop
- Measured results are displayed in a spreadsheet for easy reference and comparison, and saved in csv format for easy export to and manipulation in MS Excel
- User-specified analysis report function, providing measurement results and parameters
- Droplet calibration standard for standard view, bearing one full circle for calibration and three droplet silhouettes of 5°, 60° and 108° for periodic inspection of measurement accuracy
- Automatic recognition of drop deposition by FAMAS analysis software
- 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 x- and y-axis for exact positioning
- Adjustable level of the body and stage
- Droplet calibration standard for standard view, bearing one full circle for calibration and three droplet silhouettes of 5°, 60° and 108° for periodic inspection of measurement accuracy
