Dynotester+
Description
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 directly shows the measuring results on a comfortable display and alerts the user if defined limit values are exceeded.
Measuring Principle
Like all SITA Tensiometer, the DynoTester+ is based on the bubble pressure method for measuring the dynamic surface tension of liquids.
The principle of the bubble pressure method is, that an air stream is lead through a capillary into the process liquid. A sensor measures the pressure which is needed to generate a bubble
Application fields
- Controlling the surfactant concentration in industrial parts cleaning industry
- Monitoring the surfactant concentration in electroplating baths
- Measuring the surface tension of liquids at the plant (atline) or in the laboratory (offline)
- Quality control of inkjet inks, paints and lacquers/varnishes
- Incoming and outgoing inspections of surfactant containing goods
Mobile use for external work
