	PocketDyne Bubble Pressure Tensiometer PocketDyne at Measurement PocketDyne The first truly handy bubble pressure tensiometer The PocketDyne Tensiometer is characterized by its very simple handling, its very mobile use, and a high degree of robustness. High-precision disposable capillaries made from inert PTFE reduce the amount of time spent on cleaning and calibration to the absolute minimum necessary. High-performance rechargeable batteries allow a full day’s mobile use. Intelligent and high-quality internal components permit the rapid and comfortable recording of measuring data for determinig the surface tension, its storage and calibration. The ergonomic design allows measurements to be made in any type of sample vessel with one hand only. The intelligent use of modern technology permits the first evaluation of the direct bubble pressure measuring signal that is truly independent of the immersion depth and therefore optimal adaptation to the measuring problem. A choice can be made between the output of the true surface age or the bubble frequency. The built-in microprocessor makes the PocketDyne into a software-controlled handheld bubble pressure tensiometer. The instrument is controlled solely by three large function fields. Measurements are started without first having to define parameters. The results are shown on the large, easy-to-read graphics display. Measuring data is stored automatically when the measurement has been completed. Applications: · Monitoring of the surface tension of surfactant or wetting agent containing · baths in washing, detergency, degreasing and electroplating · Development of formulations in which surface-active substances are to be used · Field service, mobile use in production · Checking the surface tension as a quality assurance criterion for inks, rinses, · and other critical dynamic products · Determining the kinetics of the solubility, diffusion, and adsorption of surface-active · substances
	K100MK2 - a further development of the successful universal tensiometer The new K100MK2, a logical development of the well-known K100 Tensiometer has in comparison to its predecessor several additional features such as a static eliminator which ensures that sensitive measurements are not influenced by interference from electrical charges. Important measuring data can be shown continuously via an optional graphics display in the control panel. The technical data has been improved even further. For example, the range of movement and speed of the sample table have been considerably extended: measurements can be carried out more rapidly on even larger samples with improved ergonomy. Contact angle measurements on single fibers with the K100SF With the K100SF a new tensiometer and contact angle measuring instrument is now available that convinces with its functionality and measuring accuracy. The K100SF combines the technique of the K100MK2 with the precision of a microbalance system: As well as the possibility of carrying out contact angle measurements on extremely thin single fibers the K100SF offers the complete range of functions of a tensiometer with a least reading accuracy of 0.0001 mN/m. This means that it is also optimally suitable for use in standard applications. New! LabDesk V. 3.0 Now also for Drop Volume Tensiometer DVT30 The latest version of the KRÜSS measuring and analysis software LabDesk V.3.0 now also includes an add-in for the Drop Volume Tensiometer DVT30. In addition to the improved graphical presentation the extended functions now include direct visualization of the measuring results in tabular form. Further functions such as outlier recognition and definable stop criteria based on the standard deviation ensure an even better quality for your results. TC40 – the new thermostatting chamber When used for thermostatting purposes, thermoelectric heating elements (Peltier elements) fascinate with their dynamics and precision. KRÜSS has now adapted this technology for contact angle measurements and has paid particular attention to uniform temperature distribution within the chamber. A specially arranged heat conducting hood ensures that not only the sample is at the correct temperature but also the liquid used for the measurement. And this is possible through a very extensive temperature range of –30°C to +160°C ! Practically oriented details such as variable gas flow between the inner and outer windows to avoid condensation, the built-in sample slide which allows the needle opening to be minimized, the high-precision adjustment of the inner sample table with a movement range of +/- 10mm which allows the reproducible positioning of the sample without having to open the chamber and thus destroy the temperature equilibrium, the optional opening for additional cooling media or selective setting of the atmospheric humidity, and, of course, the particularly practical drawer shape of the chamber round off this product. With the TC40 KRÜSS shows how modern thermostatting for contact angle measuring instruments should be.
