Principle
The instrument adopts the ring method test method, pulls up the liquid film through the platinum ring to measure surface tension, adopts the scientific tension value correction method, and uses the standard material to correct to ensure the Test accuracy.
Applications
Electric power industry, ink, inks industry, cleaning agent industry, auxiliary agent industry, cosmetics industry, Eletroplating industry, pesticide industry, paints, Spreader industry, water treatment industry, oil production industry, fire protection industry, major universities
Standards
SY-T5370 "Determination of surface and interfacial tension", GBT 18396-2001 "Determination of surface tension by natural Latex ring method", GBT6541-86 "Determination of oil-water interfacial tension in petroleum products (ring method) ", "QB-T 1323-91 Determination of detergent surface tension", JB/T9388, ISO1409
Steps
1. After the instrument is unpacked and taken out, put it on the test bench, install the foot, and adjust the foot to make the instrument reach a horizontal state
2. Hang up the platinum ring, turn it on and it can be used normally.
3. How to use the computer software: connect the computer to the instrument, install the surface tension measurement software, and open the software to use the computer for test operation
Notice
• Ensure the level of the instrument before use
• The platinum ring needs to be corrected with reference materials when it is used for too long or polluted
• Computer software is an optional function and needs to be installed separately
