A surface tension meter measures surface tension of liquids and between two liquids, using the ring or plate method
The K20 Force Tensiometer is a stand-alone, semi-automatic instrument for all routine quality control tasks involving surface tension and interfacial tension. The instrument's precision force sensor and the accurately shaped measuring probes ensure reliable results, while processor-controlled analyses based on measurement templates provide for user-independent results. The option of long-life battery operation without a computer enables the K20 to be used flexibly on site.
A drop volume tensiometer is a device used to measure surface tension, which is the force acting on the surface of a liquid that tends to minimize the area of the surface. The instrument is particularly designed to analyze the surface tension of liquids by measuring the volume of liquid in a droplet formed at the end of a thin tube or needle.
