Chamois Metrology, in partnership with Nichesensor, has announced a new range of low and ultra-low pressure transmitters designated the DS, DT and DV, for flow and level measurement. They feature standard ranges between ±5 mbar and ±2 bar and are available in both uni-directional and bi-directional configurations. With a construction that makes them ideal for use in demanding and hostile environments, they have an accuracy of up to 0.15% and can operate between –40°C and 125°C.

Narda Safety Test Solutions has now equipped its Selective Radiation Meter SRM-3006 for frequency-selective measuring of electromagnetic fields with a "Scope" operating mode. Using this, it is possible to analyse the frequency content and time characteristics of signals from, for example, radar equipment and mobile communications services. It is possible to measure pulse widths and signal periods as well as set triggers, just like with an oscilloscope. For more details, e-mail support@narda-sts.de; or see www.narda-sts.com.
Numerical Algorithms Group (NAG) has announced an updated version of numeric routines for graphics processing units (GPUs) that are used in Monte Carlo simulations in a variety of applications. This latest release contains routines for Monte Carlo simulations – Quasi and Pseudo Random Number Generators, Brownian bridge, and associated statistical distributions. NAG's numerical routines for GPU computing are available to academic researchers involved in collaborative research with the NAG organization.
