Overview
The JYW-200A surface tensiometer is a practical instrument directly controlled by the host, with a resolution of 0.1mN/m. The instrument is equipped with an English version for export use, with optional voltages of 220 volts and 110 volts.
Features
1. Adopt the ring test method to correct the platinum ring through the reference material, eliminating the need to replace expensive parts.
2. Integrated molding housing and precision direct drive mechanism to improve Reliability and durability.
32-Bit ARM high-end microcontroller control, fast operation speed, high accuracy.
4. American ADI 24-bit AD converter, accurate force value acquisition.
5. Improved torque wire lever structure to ensure Linearity testing.
6. High-end LVDT Displacement Sensor, to ensure the repeability accuracy.
7. Automatic stop function, the tension value is automatically displayed after the test is completed.
8. Automatic averaging function to reduce operation workload.
9. Digital LCD display, split-screen display of real-time values and test results.
Principle
By measuring the force of the liquid on the platinum plate, using physical phenomena such as bubble pressure and droplet shape, the liquid surface tension value is calculated.
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", GBT 6541-86 "Determination of oil-water interfacial tension in petroleum products (ring method) ", QB-T 1323-91 "Determination of detergent surface tension"
Steps
1. The instrument is unpacked and taken out and placed on the test bench.
2. Install the ground feet and adjust the level of the instrument.
3. Hang the platinum ring.
4. It can be used normally when powered on and turned on.
Notice
• Make sure the instrument is placed horizontally before use.
• Platinum rings need to be regularly corrected with reference materials to maintain accuracy.
• Power supply voltage selection (220V or 110V).
