K20 – Semi-Automatic Force Tensiometer
The versatile semi-automatic tensiometer for quality control
The K20 is a semi-automatic instrument designed for routine quality control of surface tension and interfacial tension. It features a precision force sensor and well-shaped measuring probes to ensure reliable results. Processor-controlled analyses using measurement templates deliver user-independent results. Its long-life battery option allows flexible use on-site without a computer.
Applications
☑️ Aging status check of transformer and other oils (ASTM D 971, IEC 62961)
☑️ Detection of cleaning agent residues in food and other industries
☑️ Validation of surface tension for cleaning and wetting agents or surfactants
☑️ Quality assurance of emulsifiers
Measuring Methods
☑️ Surface and interfacial tension via tensile force of lamellae under or stretched from a ring
☑️ Surface and interfacial tension via wetting force on a platinum plate or rod
☑️ Liquid density by buoyancy of an immersed probe
☑️ Aging checks of oils using interfacial tension following ASTM D 971 and IEC 62961
Measuring Results
☑️ Surface tension of liquids
☑️ Interfacial tension between liquids
☑️ Liquid density
☑️ 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.
