Allroud Tensiometer for Analysis and Optimasation


The compact all-round tensiometer measures the dynamic surface tension in three different modes: Single, Auto and Online. This gives it all the functions for a wide range of measuring tasks such as the analysis of wetting behaviour, concentration control or determination of the influence of temperature.


• Concentration quickly controlled

• Fast and reliable for control tasks

• Measures a value at defined parameters



• Comfortable mode for R&D

• Automated scan of surfactant dynamics

• Characterisation of wetting behaviour



• Automatic continuous measurement over a period of time

• Continuous process monitoring

• Analysis of temperature influence



Surface tension in mN/m

Fields of application

Analysis of the wetting behaviour of surfactants or surfactant-containing products

Control of surfactant concentration

Investigation of temperature dependence for cloud point analysis


3 Modes: SINGLE (one-point measurement), AUTO (automated scan), ONLINE (continuous measurement)

Robust housing and optional acid protection

Easy rinsing and calibration with water


Capillaries for process use made of PEEK, PTFE or glass

Independent of immersion depth due to differential pressure method

Independent control of the parameter bubble lifetime

Measurement monitoring

Water (DI) as calibration standard


Industrial parts cleaning, electroplating, paints & lacquers, inkjet inks and many more


SITA tensiometers have been in use for over 25 years for these applications, among others:

Control of surface tension and surfactant concentration in industrial parts cleaning
Monitoring of the wetting agent concentration in galvanic coating and etching processes
Quality inspection of ink-jet inks as well as paints and varnishes
Measuring surface tension on the line or in the laboratory

Product development for cleaning, electroplating, inks, paints, etc.

Analysis of the temperature behaviour of process chemicals

SITA application consulting develops measurement methods and control procedures for individual use in close consultation. This includes free trial measurements, characteristic curves, rental positions and consultations remotely or on site.

Measuring principle

Like all SITA Tensiometer, the SITA pro line t15+ is based on the bubble pressure method for measuring the dynamic surface tension of liquids.

Therefore, as it can be seen in the picture, an air stream is lead through a capillary into the process liquid and the pressure development for the bubble generation is measured. (read more ...)
