This measuring device is ideal for the fast determination of humidity rate in solid substances such as wood and building construction materials.

Dehydrating breathers are being used for liquid immersed transformers in order to protect the insulating liquid and prevent the harmful moisture absorption from ambient air, which occurs when the load on the transformer fluctuates.The dehydrating breather removes practically all moisture from the air that flows through it into the conservator when the transformer is cooling down. This largely prevents any reduction of the dielectric strength and the formation of condensation in the expansion tank. Thus, the dehydrating breathers increases the operational safety of transformers.

The test strips are a practical, cheap and safe way to check moisture. This means that the exact humidity inside the packaging can be read from the color display. Depending on the level of moisture, the color on the test strip changes from "dry" to "moist". Environmentally friendly moisture indicators For packaging of electronic components 2004/73 / EC (requirements of EU environmental protection) Cobalt has been listed as a carcinogenic substance in EU environmental protection regulations since 2004. Only test strips that comply with the regulations may be used within the EU. The test strip is divided into several tone value points. Depending on the humidity, the color changes and you can read off the exact degree of humidity in%. The previous test strips (color change from blue to red) are prohibited. 2004/73 / EC (requirements of EU environmental protection)

Moisture analysing is an integral part of production and processing of many raw and finished products and has a crucial impact on the quality of the product. Moisture analysers are used particularly in the food industry, water resource management (sewage plants, etc.), plastics industry, agriculture and the energy industry (bio-energy plants, etc.). Determining moisture requires a great deal of experience. Depending on the type of sample and the task involved, various drying processes are used. Sample is evenly warmed from above, without risk of burning the sample surface Affordable purchase costs ensure rapid amortisation of the device Most common temperature ranges from 35 – 200 °C High measuring precision, up to 0.01 % Sufficient buffer capacity, weighing capacity up to 200 g Various drying programs (soft drying, standard drying, drying in levels, rapid drying (Boost)) The

Microwave measurement device, Continuous In Line measurement of dry matter The measurement is contactless, the measured values of the %, %H2O,%TS, Bx, g/cm3, g/l or mg/l content are available as digital and analogue values. The HK2 is applicable in different industries like sugar, sewage plant and building material industry. Because of further increasing quality requirements after ISO and EU standards, the industries have an enhanced demand for improved quality control, standardization and InLinetrend observation.

Microwave measurement device, Continuous InLine measurement of dry matter or consistency Description At the microwave measurement technology an electromagnetic wave with very low energy is generated. This signal is coupled via an antenna into the product (Cellulose, Cheese, Milk, Curd, etc.). Depending on the dielectric properties of the product the signal propagates in the product. After the signal has passed the product a second antenna receives the signal (Transmission). Amplitude and phase shift of the received signal are an expression for the consistency, water content or dry matter of the product. The microwave measurement is very stable and it has a quick response to product changes.

NIR LED– Technology, Continuous InLine density measurement Description The HK8 Series are NIR (Near Infrared) LED InLine measurement devices with state–of–the–art technology. The devices are used on conveyor belt, in pipelines (connection via flowthrough measuring cell or flange) and in tanks / vessel. Through the modular construction (Sensor and evaluation unit are separate), the sensor can be installed at a difficult accessible places and the evaluation unit can be installed at a well accessible place. This ensure the easy handling. The modular construction makes the operation of the HK8– Series very easy.

Microwave Resonator, Continuous In Line Moisture measurement Description The microwave resonance measurement uses the electromagnetic energy stored inside a resonator to determine the water content of a product. Via a non conducting window, the resonator field is coupled into the material located in front of the resonator. This so called leakage field is not radiated. Depending on the dielectric properties of the product, the shift of resonance frequency and bandwidth of the resonator is used for measurement. The ratio of bandwidth and frequency shift is density independent. The measurement is highly suitable for bulk material.
