Product Description
MIL-II Contact Angle surface tension meter
The instrument is mainly used to test liquid surface/interfacial tension values. The contact Angle test and wetting analysis of thin film were completed. The instrument is widely used in cleaning agent, ink, paint, coating, water treatment, pesticide, electroplating, chemical aid, cosmetics, transformer oil and other fields.
The experimental method of obtaining the surface tension coefficient of a liquid by measuring the force required for a metal ring of known circumference to break away from the surface of the liquid to be measured is called the pull-off method. The instrument application of hall sensor, combined with the gradient magnetic field. The type of displacement force transducer, reflect the force and displacement and magnetic induction intensity of the relationship between the three physical quantities, by using four and a half digital display instrument millivolt values, the intuitive is good, through the sensor of weighing instruments, implements the non-electricity measurement, can satisfy the need of measuring liquid surface tension.
Standards refers to: GB/T14216, ASTM D5946, ISO15989-2004 Plastics - Film and sheeting - Measurement of water-contact angle, ISO8296:2003 Plastic-film and sheeting -Test method for wetting tension.
