The versatile semi-automatic tensiometer for quality control.
to read more details
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.

Sample temperature
The quick and simple manual operation of the sample stage and the large, illuminated sample chamber allow for swift positioning of the sample vessel. Then one of the prepared measurement programs moves the motorized sample stage and records the measurement results. The speed and other parameters can be easily optimized for the specific range of values of your particular application.
An optional thermostat jacket enables process conditions for temperatures between ‑10 and 130 °C to be exactly simulated. When testing dispersions, an integral magnetic stirrer ensures that the sample is homogenous before the measurement is carried out.
As an extension of the instrument’s internal storage, you can transfer results and related parameters to optional software. Alternatively, a report containing the results can be output to a printer at the press of a button.
