Product Parameters

Q1: What is the testing principle of this dyne pen?
A1: It uses a special chisel tip to evenly apply a test liquid with specific surface tension. By observing whether the liquid film retracts within 2-4 seconds, it quickly determines if the material's surface tension meets the standard.

Q2: Which industries and materials is it suitable for?
A2: It is widely used in mobile phone casings, films, automotive parts, glass, plastic printing, coating, and other industries to test the surface tension of various materials like plastics, glass, and metals.

Q3: What does the model number (e.g., 38#) mean? How to choose?
A3: The model number represents the surface tension value of the test liquid (unit: mN/m). For example, the 38# pen has a tension of 38 mN/m. Selection is based on the required standard value of your process.

Q4: How to interpret the test result?
A4: Draw a line on a clean sample surface. If the liquid film remains continuous and intact without retracting for 30 seconds, the sample's surface tension is higherthan the pen's value. If it retracts and forms droplets, the sample's surface tension is lower than the pen's value.

Q5: What should I pay attention to during testing?
A5: Ensure the test surface is absolutely clean and free of grease; recap the pen immediately after use to prevent evaporation; never mix or use pens of different models interchangeably.

Q6: What is the capacity of a single dyne pen? Approximately how many uses?
A6: A single pen has a capacity of 7ml. Depending on frequency of use and stroke length, it typically can be used for hundreds of tests.

Q7: What are the precautions when using the dyne pen?
A7: Store in a generally ventilated, cool, and dark place. Avoid exposure to direct sunlight and do not store in a refrigerator. An environment of 20-25°C with 40-60% RH is optimal.

Q8: Where is it manufactured?
A8: This dyne pen is manufactured in Germany and is a product of the German brand SHEELON.

Q9: What are the advantages of the chisel tip?
A9: The hard fiber chisel tip is tough and wear-resistant. The 7mm width allows it to draw a uniform liquid film, making the test results clearer and more accurate.

●Review: 'We switched to this brand for consistency. While the unit price is higher, the shelf life and reliability mean we waste less and have fewer production hiccups. Worth the investment.'

Rating: ★★★★☆ (4.5/5)

●User ID: Lab Technician
●Review: 'Incredibly easy to use and the results are immediate. The ink flows consistently from the fibrous tip. A must-have tool for any lab dealing with surface treatment.'

Rating: ★★★★★ (5/5)

●User ID: Film Production Operator
●Review: 'We use them daily to check corona treatment. The 7mm wide line is much easier to see than from a fine tip. These are durable and survive in a pocket on the shop floor.'
