The cleaning performance of textiles depends on the concentration of active agents in the soap water. But at present, the concentration of the active agent is not equivalent to the cleaning agent. One of the problems is that the consumption of active agent depends on many factors such as tank load, temperature, degree of contamination and type of contamination. In addition, the consumption of the active agent and the effect of the active agent will inevitably be affected when the textile is cleaned. Knowing the active agent concentration in a single wash and rinse cycle is necessary in order to achieve a high quality in the optimization of the wash cycle and detergent supply to the washer.
Surface activity is the most important characteristic of active agents, and its performance by measuring surface tension can provide a feasible analysis of active agent concentration. Static surface tension testing methods such as the ring and platinum plate methods cannot be used for this analysis because this method cannot accurately and reproducibly analyze the dynamic surface tension of the cleaning process. In addition, static test devices require complex cleaning methods after the test. SITA's Surface Tensiometers are based on the bubble pressure method, which provides a range of high dynamic to quasi-static surface tension measurements.
Model SITA Dyno Tester is a portable and lightweight Surface Tensiometer. Can monitor washing and rinsing in the laundry room and can also be used as laboratory equipment to provide a quick and easy yet accurate test. By comparing the test results with the required value, further convey information on whether the active agent needs to be added.
The USB interface transfers data to the computer, and can also realize various functional operations, and can also be used as an external power supply. The instrument also has a rechargeable, 10-hour fully charged battery, which can also be recharged via USB.
The T60/2 SITA Surface Tensiometer online is a suitable test device for optimizing the cleaning process and analyzing and reminding the addition of detergent during the laundry process.
Software and interfaces allow easy transfer of data to a computer for better analysis . Among all SITA tensiometers, the online T60/2 automatically measures temperature and surface tension at the same time, so it can analyze especially those active agents that are sensitive to temperature. Further instrumental advantages are simplicity and technically uniform design.
