We are developing a novel gravimetric moisture measurement system for wood based materials. The measurement principle is based on combining the Loss on Drying (LoD) method with complementary water loss detection systems. In our setup, air flows throu

Industrial grade platinum resistance thermometers were calibrated in the temperature range from $$200\,^{\circ }\mathrm{C}$$ to $$700\,^{\circ }\mathrm{C}$$ . Both wire-wound and thin-film sensor-based thermometers were investigated. The purpose of t

The SI unit of mass will probably be redefined within the next few years using an invariable natural constant. Nevertheless, dissemination of the kilogram will still be realized by weighing using physical weights prone to contamination. Published dat

The pressure balance used for MIKES barometer calibrations is a DH Instruments PG7601 for the range 5 kPa–350 kPa. The commonly used pressure range in barometer calibrations 850 hPa–1050 hPa has been automated by a removable weight exchange syste

Temperature gradients were studied in two different pieces of density calibration equipment. Density is determined by hydrostatic weighing in water. The temperature of water and the surrounding air was determined with six temperature sensors. Also de

We have developed and characterized a force measuring system that is able to measure small forces down to 50 nN. The force measuring system and the characterizing method are described, thoroughly tested and analysed. The force measuring system consis

A micro machined capacitive silicon scale has been designed and fabricated. It is intended for weighing masses on the order of 1 g at the resolution of about 1 ppm and below. The device consists of a micro machined SOI chip which is anodically bonded
