For moisture or dry substance determination of powders, granulates and solids, the NIR measurement technique is often the most practical method for fast analysis. This technique is based on the principle that a specific wavelength of infrared light is absorbed by water. Within seconds our laboratory and at-line instruments determine the moisture percentage of a product. Our on-line sensors measure directly real-time continuously and makes direct process control possible. In addition to moisture measurement, this technique is also capable of measuring for example fat/oil and protein levels in a product. The most common applications are found in the food, wood, paper, pharmaceutical and chemical industries, but in many other industries we have solutions when it comes to moisture measurement and control.

Our systems are based on two different NIR techniques. The first one is a filter based technique where a pre-defined set of NIR filters are used to measure at fixed wavelengths. The second technique is a full spectrum measurement. We are able to advise which technique and instrument is the best solution for your application.

For moisture measurement in liquids, a microwave or radio frequency technique is the best way to measure the concentration or dry substance. The microwave technique is based on the principle that microwaves are absorbed by water. This technique for concentration measurement is very suitable for liquids and slurries like milk, molasses, coffee solutions, creams etc.

The technique used for moisture measurement based on radio waves uses the principle that radio waves are damped and shifted in phase by different materials. This is due to the fact that every material has its own dielectric constant (electrical conductivity). This method is called RF (Radio Frequency) technique. We supply handheld meters, on-line and at-line process sensors. We also supply a system for measuring the complete moisture profile of boards.

Applications for our radio frequency systems are found in producing building materials like gypsum boards, wood boards, fibre plates and also in the food industry (for example caramel).
