Device size, price, minimum class! Wettability testing based on contact angle values is possible anywhere and by anyone.
The "ST-2" is a portable contact angle meter that excels in portability and can be used for measurements in outdoor locations where power supply is not available or where tabletop devices cannot be brought in. 【Features】 ■ Enables wettability testing based on contact angle values ■ Suitable for measuring samples that cannot be cut out ■ Capable of measuring on substrates with warps and unevenness ■ Portable and small contact area allows for quick measurements on-site ■ Does not require utilities (excluding batteries for the light source) With the extended Bikerman method, it can now measure angles exceeding 90°, which was not possible with the previous model "ST-1," and can also be used for evaluating hydrophobicity.

Applications/Examples of results
【Applications (Partial)】 ■ Substrates that cannot be cut out: Glass panels, car bodies ■ Samples with recesses: Petri dishes, concave lenses, sanitary ceramics ■ Anti-fog evaluation: Eyeglass lenses, visors, window glass ■ Cleaning evaluation: Wafers, glass panels, hard disks ■ Surface modification evaluation: Plasma, UV, corona discharge ■ Coating evaluation: Anti-fouling, hydrophilic, hydrophobic, oil-repellent, clear, low friction ■ Outdoor: Pesticides on leaves, functional coatings for building materials and operation panels ■ Replacing wetting tension tests using wetting reagents with quantitative evaluation based on contact angle values - Transitioning from qualitative evaluations prone to personal error to quantitative evaluations based on contact angles - Liberation from the selection of wetting reagents, concerns about quality over time, and running costs of consumables ■ Various equipment manufacturers and coating contractors - When proposing cleaning equipment and surface modification equipment, clients often request the inclusion of portable contact angle meters for performance evaluation... - There is a demand for on-site proof of the finish and coating performance (such as hydrophilicity, hydrophobicity, anti-fouling, etc.) after coating...
