The versatile semi-automatic tensiometer for quality control

Force Tensiometer – K20 for surface and interfacial tension in quality control
  • PRODUCT
  • SPECIFICATIONS
  • ACCESSORIES

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.

Applications

  • Checking the aging status of transformer and other oils according to ASTM D 971 and IEC 62961

  • Checking for cleaning agent residues in the food industry and other areas

  • Surface tension validation for cleaning or wetting agents as well as other surfactants

  • Quality assurance of emulsifiers

Measuring methods

  • Surface tension using the tensile force of a lamella underneath a ring

  • Interfacial tension using the tensile force of a lamella underneath a ring

  • Surface tension using the tensile force of a lamella which is stretched until it disrupts

  • Interfacial tension using the tensile force of a lamella which is stretched until it disrupts

  • Surface tension using the wetting force of a liquid at a platinum plate or rod

  • Interfacial tension using the wetting force of a liquid at a platinum plate or rod

  • Density determination of a liquid using the buoyancy of a probe immersed in the sample

Measuring results

  • Surface tension of a liquid

  • Interfacial tension between two liquids

  • Density of a liquid

  • Sample temperature

Easy handling and preparation

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.

 

 

Adaptable for different measuring conditions

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.

 

 

Additional options for data storage

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.
