The versatile semi-automatic tensiometer for quality control
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.
