Kibron AquaPi - a battery operated, portable tensiometerThe Kibron AquaPi is the first battery operated and portable tensiometer, rugged enough for field operations and on-site measurements. With AquaPi you can measure surface tension easily and rapidly, practically anywhere. The sensitivity and precision of AquaPi is unmatched, just see the Application notes in the section Technical specifications. AquaPi is very fast and easy to use, requiring no special training. The calibration time is short and the measurement is done in less than 30 seconds, with a clear digital readout for surface tension values. The standard cuvette volume is only three milliliters. The single-use cuvettes ensure accurate results, eliminating the risk for contamination. AquaPi is excellent for basic surface chemistry research and educational use. Further, it is ideal for on-site monitoring of water quality, providing immediate alert for the presence of e.g. solvents, oil, and detergents in ground water samples.
