The mobile hand-held Tensiometer measures the Surface tension as well as the surfactant concentration easily and quickly in the laboratory and at the production line. It shows the measured values directly on the comfortable display and alerts if set limits are exceeded or not reached - for process monitoring and quality control.
MOBILE
- Small, light and mobile without PC or laptop
- Battery capacity up to 10 h
- Practical case for transportation and storage
PRACTICAL
- Simple measurement at the touch of a button
- Fast check of the surface tension
- Capillary optimised for process use
PRECISEE
- Display of surfactant concentration with range limits
- Measured values comparable with all SITA tensiometers
- 50 measuring profiles for tasks ranging from from bath control to process documentation

SITA tensiometers have been in use for over 25 years for these applications, among others:
- Control of surfactant concentration in cleaning and rinsing baths in industrial parts cleaning
- Monitoring of the wetting agent concentration in galvanic coating and etching processes
- Measuring the surface tension of liquids at the plant or in the laboratory
- Quality testing of ink-jet inks as well as paints and varnishes
- Incoming and outgoing inspection of surfactant-containing products
- Mobile use in the field and in the production area
SITA application consulting develops measurement methods and control procedures for individual use in close consultation. This includes free samplel measurements, characteristic curves, rental positions and consultations remotely or on site.
Like all SITA Tensiometer, the DynoTester+ is based on the bubble pressure method for measuring the dynamic surface tension of liquids.
For this purpose, an air stream is lead through a Capillary into the process liquid. A sensor measures the pressure, which is needed to generate a bubble.
| Bubble lifetime | ||

| Adjustable range | (15...30,000) ms | |
| Resolution | 1 ms | |
| Max. regulation deviation | 5 % | |
| Measuring deviation | max. 1 ms | |
| Power supply | ||
|---|---|---|
| USB | (100...240) V / 5V | |
| Li-Ion battery | 3.6 V / 2,000 mAh, min. 10h operating time | |
| Max. power consumption | ca. 2.5 W | |
The software SITA LabSolution provides convenient access to all functions and data of the SITA DynoTester+ with the PC. Measuring parameters can be set conveniently and data can be read out from the measuring device.
