Economical introduction to tensiometry
This revised model incorporates new technology and new design and is especially suitable for newcomers to the world of tensiometry, or for practical experience in schools or university
Lauda says that hundreds of TD 1 tensiometers have been sold throughout the world since market introduction 1991 The demand for economical, easy-to-use tensiometers continues

The Lauda Integral XT process thermostats received their market launch in 2006 and since that date have established themselves firmly among users
The TD 1 C units, whose technology has been completely revised and which bear a new design, offer even easier handling due to the handy, removable command console which has proven itself with Lauda thermostats and measuring instruments, says the company.
Especially suitable for newcomers to the world of tensiometry, or for practical experience in schools or university, is the TD 1 C model with du Nouy ring and Wilhelmy plate according to international standards (DIN 53914, ISO 304, ASTM D971).
Furthermore, the density, according to the Archimedes principle up to 2000kg/m3, and smaller weights up to 5000mg can be measured due to a newly-developed, even more powerful force-measuring cell with a considerably enlarged measuring range.
The measuring table with the sample stage can be moved up and down in the complete absence of jolts and play by means of ergonomic adjusting screws, like a microscope, in order to lower the Wilhelmy plate to the sample surface or in order to determine the force maximum during the ring measurement.
By means of the high-resolution display of the command module, the increase in wetting force during withdrawing of the ring can be followed and the maximum force can also be found without detaching the lamella.
The value displayed in the maximum is automatically corrected according to Zuidema and Waters, and thus corresponds to the surface tension of the measured liquid in mN/m.
Surface tensions up to 300mN/m can be measured with a resolution of 0.1mN.
At the touch of a button, the measured value and all parameters can be either saved or directly printed out on an optional protocol printer.
Thus the TD 1 C tensiometer offers ambitious analysis in combination with easy operation, says Lauda. Request a free brochure from Lauda ...
