The JK99 series fully automatic force tensiometer uses the platinum plate method and platinum ring method (Du Noüy ring method and Wilhelmy plate method). It is an easy-to-use testing instrument that uses physical methods instead of chemical methods to perform surface/interface tension measurement. It features automatic zeroing and fully automatic measurement by the press of one button. It can quickly and accurately measure the surface tension of various liquids and the interfacial tension between liquids. The computer software is compatible with different models in this series. No additional training is required when different models or configurations are in use.
Below is the list of JK99 models.
