TEWS Elektronik instruments in their laboratory versions are used where immediate results, the highest precision and the use of a sample size that is sufficiently representative are required. Where other traditional methods such as drying oven, thermo-balance or Karl-Fischer take too much time, or the sample size used is not representative. The results obtained by Tews are independent of the natural fluctuations of the products, such as color, particle size, salt content or density of the material. The handling of the compact devices is very simple, which is why the possibility of error in the manipulation of the samples is practically avoided. The results can be archived or transferred to the PC or network, or to a USB memory. For the adaptation of the instrument to the exact requirement of the client, we have many different humidity sensors. With tubular type sensors, density measurement is also possible.

It does not require preparing the samples

The measurement method developed and patented by TEWS Elektronik allows to determine the humidity of the sample instantaneously and without the need to prepare it previously. Typical work on samples such as grinding, sieving, weighing before and after analysis, use of chemical reagents …, are not necessary. Moreover, our analysis is non-destructive, the product sample is not modified or heated and therefore can continue to be used.

Measurement in seconds

The measurement is done in a few seconds. As soon as the sample is introduced into the sensor, the result is indicated on the screen and filed. Thus, considerable savings of time and money are obtained.

Evaluation of values

The values obtained in the instantaneous measurement are recorded in the instrument’s memory, together with the date and time and other data of the process. Data that is displayed at any time on the screen of the equipment itself or an external PC, in addition to being able to perform a statistical analysis, or obtain documentation of the calibration or a graphic representation of the course of the values.


The MW1150 is a compact instrument for laboratory use and “at-line”. It is built based on MW 11XX type technology. This allows measurements in milliseconds, providing the values quickly and reliably. The measurement results are displayed on a backlit 5.4 ” screen. Up to 200 measurements can be stored in the instrument. Through the program “TEWS MOISTURE VIEW LITE” it is possible to transfer the values through a standard port to a PC. A P1150 printer connection is available, as well as the connection for different temperature sensors. The MW1150 instrument is available in many versions with different sensors that adapt to each type of product to be analyzed.


The laboratory instrument type MW4300 is equipped with a 10.4 “color touch screen. The MW4310 requires the connection of an external screen, keyboard and mouse. Both instruments run under the included TEWS MOISTURE VIEW Software.

The MW4300 and MW4310 make up the top range of our laboratory instruments and are combinable with an infinite number of sensors, depending on the type of material to be analyzed.



The MW4420 is a moisture and density analyzer station in cigarettes, filters, etc. The measurements are made completely automatically millimeter by millimeter throughout the sample. The values obtained by the equipment allow to know the humidity and density “profile” of cigarettes, filters, multi-filters, etc., and derived from the above, the determination of the dense point, determination of the cut-off point, etc.


The MW4430 is a moisture and density analyzer station in cigars. Both parameters are obtained automatically and instantaneously and are displayed on the screen in the form of a graphic and a table. The humidity and density parameters are shown millimeter by millimeter over the entire length of the cigar, as well as the average value of each piece. The method is non-destructive and allows knowing – without destroying the cigar – if the cigar smoke will be of good quality, both because of the humidity of the cigar and because of its draft (suction), which is particularly important in handmade long-gut cigars, where each one is a unique piece different from the others.
