AQ Guard Smart 2000 is a measuring device designed to measure particle concentrations in the ultrafine range, which typically cannot be detected by optical aerosol photometers or spectrometers due to their small size, but which have a significant impact on health according to the WHO.
Most flow meter suppliers recommend 10 to 40 x pipe diameter straight length piping before the inlet. No obstructions allowed! The Vögtlin d·flux multi-parameter mass flow meters do not need this. Due to the built-in flow conditioner, you can build 2 elbows in 2 different places directly in front of the d·flux without influencing the accuracy. Features: • Elbows/bends upstream of the instrument? Not a problem! • Advanced design removes any flow turbulence! • Space saving – no straight inlet
The art depot Boijmans Van Beuningen in Rotterdam (Netherlands) focuses on sustainability in numerous areas. Accordingly, the cooling water system also had to fit into the building‘s sustainability concept. aquatherm blue pipe made of polypropylene (PP-R) convinced the designers with its significantly lower CO2 emissions compared to steel pipes. Due to its technical properties, the piping system is also optimally suited for refrigeration installation.
Remote work via secure VPN access is more important than ever. New technologies, increasing networking and flexible working models are changing the way we work. Companies that need to ensure business continuity are also at risk due to external circumstances such as severe weather or pandemics. There is no better time than now for companies to rethink their VPN strategy.
Air flows due to wind are irregular and cause pressure fluctuations on the building. Overpressure occurs on the side of the building exposed to the wind, while suction occurs on the side away from the wind. These fluctuations also influence the BlowerDoor measurement. Learn more about BlowerDoor measurement in windy conditions in our January newsletter!
The highlite has been the opera “Notre Dame” by the composer Franz Schmidt. Due to corona restrictions the orchestra and the Prague choir had to be transmitted by fibre optics from the theatre's concert hall to the open-air venue in the cloister courtyard. The responsible sound engineers Stephan Linde (choir /soloists) and Benjamin Schultz (orchestra) underlined, that the used for the transmission cardioid plane mics KEM 975 ideally kept the crosstalk between orchestra and choir to a minimum.
To support the demand for smaller and miniaturized multi-sensor devices, trinamiX has introduced PbS and PbSe Multi-Pixel detectors. These are available with up to 16 pixels on a single chip. Due to the small chip size and the patented encapsulation technology, the detectors can be directly mounted as bare chips on a Printed-Circuit-Board (PCB), making the Multi-Pixel detectors particularly suitable for highly compact, price-sensitive application-specific spectroscopic devices.
