• Battery capacity up to 10 h
• Practical case for transport and storage
PRACTICAL
• Simple measurement at the touch of a button
• Fast control of surface tension
• Capillary optimised for process use
PRECISE
• Display of surfactant concentration with range limits
• Measured values can be compared with other SITA tensiometers
• 50 measuring profiles for tasks 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 (atline) or in the laboratory (offline) | |
| • | Quality testing of ink-jet inks as well as paints and varnishes | |
| • | Mobile use in the field and in the production area | |
| • | Incoming and outgoing inspection of surfactant-containing products | |
| 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. |
