Innovative Microwave Resonance Technology Process and Laboratory Moisture Measuring

The experts for moisture, density and mass measurement with microwaves.

Dear Customer, We are pleased to introduce ourselves to you as the next generation of managers of TEWS Elektronik. After successfully leading the company for 43 years, Mr. Manfred Tews retired last year, and his son, Mr. Andre Tews succeeded him as the company’s Chief Executive thus continuing the family-owned tradition of TEWS customer-oriented technical excellence. After he joined TEWS in 1999, Mr. Andre Tews had managed the business jointly with this father. They include the handheld MW 1100 devices, the MW 1150 and MW 43XX lab series, the inline MW 42XX systems, the high-speed MW 301X units,...

Measuring Moisture by Microwave Resonance The Patented „TEWS Method“ Moisture Moisture is defined as the percentage of water contained in the total mass of a solid substance. Other terms are used synonymously - such as humidity, material moisture, absolute moisture, moisture content, gravimetric water content etc., these words must be clearly distinguished from all expressions referring to the share of steam in gases such as humidity, relative humidity, water vapor content etc. The ATRO moisture details only refers to the water content in the dry mass of the substance. Water molecules and resonant...

Measuring Instruments For the moisture content to be shown as a percentage, the instrument first needs to be calibrated. This is done by collecting samples of the product with different moisture contents, which cover a typical range of applications. Moisture in the sample is then measured using both a suitable laboratory method and the microwave resonance method. In the drying process (drying kiln, drying balance), the sample moisture is determined mainly by the amount of weight lost. A chemical method, such as the Karl Fischer titration, can also be applied occasionally to determine the water...

Measuring the Moisture in Foods and Feedstuffs Fast and accurate Measuring to save you Time and Money The amount of water contained in foods and primary products is vital to quality, processing and durability. The legal requirements concerning food products also need to be taken into account. Ensuring the correct product moisture at all stages of the manufacturing process requires continuously measuring the actual product or samples of it. Conventional moisture measuring involves a drying kiln or a drying balance - which often demand some preparation of samples and will always impose some delay...
