TEWS High Performance Solutions

Chemical Industry As a Partner.

Your production process combined with our patented solutions. The result: the most accurate data about the residual moisture & density of your products.



savings – due to improved dryer control



faster –in the lab due to readings within milliseconds

Process Automation


based on online moisture readings

Solutions that help companies achieve their goals faster. For over 50 years TEWS moisture & density measurement solutions have played a valuable role in the chemical industry. Our high-performance solutions combine surface and core moisture detection as well as density measurement based on the patented TEWS microwave technique.

Measurably better - No matter whether we're talking about powders or granules, flakes or boards, our high-performance solutions are simple: we provide patented microwave technique tied to passion driven services – even for products with a moisture content below 0.1%. Why? The answer is as simple as our solutions: 
to improve the production process of our clients. Or, in other words: to help our clients to achieve better results.

Our solutions have been developed and designed hand-in-hand together with the chemical industry and, therefore, fulfill all requirements e.g. in terms of ATEX. null 

The TEWS method enables the chemical companies to gain high-precision data about the level of moisture content and density of their products. It’s a one-stop-shop without any sample preparation to optimize the whole production process in terms of cost savings and quality control.

How Leading Companies Benefit From TEWS.


Water Matters.

Product quality and -efficiency can be significantly optimized by controlling the moisture content in almost all process steps. Managing the moisture of powders, granules, pellets, flakes and boards is a key factor to achieve better results. TEWS patented solutions deliver high precision results. It's what matters when it comes to company goals and how to achieve them faster.


  • High-Speed-Inline-Measurements – The continuous moisture and/or density measurements in the process help you to control your process just-in-time and to regulate and to optimize your process in an efficient way.
  • Accuracy – Depending on the type of product, we are able to measure very accurately even very dry products with measurements down to the 500 ppm area.
  • Plant Efficiency – With our measurement results operators can utilize their advanced machines at an optimum and reduce downtimes and waste to a minimum.
  • Automation – Thanks to the direct connection of our instrument to a dryer the process control can be regulated automatically.
  • Product Quality – A precise moisture level is decisive for the quality. And that, in turn, satisfies your customers and reduces their claims.
  • More Profit – Precise data of water content lead to precise prices.
  • Energy Efficiency – Precise information about moisture allows optimization of drying processes, prevents overdrying and leads to lower energy costs.
  • Storage Efficiency – Precise compliance with the recommended water content prevents mold, deformation or any quality problems in further production steps.

It Takes Two.

TEWS patented two-parameter measurement solutions enable chemical companies to work with high precise data in both ways at the same time. Data that relate to the moisture content of tobacco as well as its density. Knowing the precise weight of tobacco during the high-speed manufacturing process leads to even better results in terms of product quality and -efficiency.


  • Mass Flow and Balance Check – Accurate density information being used to assure constant filling levels.
  • Quality Control – Securing homogenity of your products e.g. tabs of washing powder. 
  • Plant Efficiency – Automatic dosing at high-speed without balance checks.
