ROUND UP

Current measurement – three phase ProSys of the UK have released a new series of 3Ø micro-flex Rogowski current probes – available from Denver Technical Products . There are three current ranges, 10 A/100 A/1 000 A, with a frequency response of 20 Hz to 10 kHz (-2 dB).The battery life is typically 1 000 hours.The probe aperture diameter is 50 mm, there are however other models available up to 100 mm. The three separate coax output cables are terminated with a safety BNC connector. Battery life is typically 1 000 hours. Enquiries:Tel. 011 626 2023 or email denvertech@pixie.co.za

New high resolution spectrometer – elemental analysis

SPECTRO Analytical Instruments has introduced its newSPECTROARCOS high-resolution ICP-OES spectrometer, the first and only spectrometer featuring the fast and convenient selection of axial plasma or radial plasma observation in a single instrument − without any optical compromise. Designed for use in the most demanding elemental analysis applications in industry, science, and academia, the new SPECTRO ARCOS easily surpasses the performance limitations of conventional ICP-OES instruments — dramatically improving sensitivity, stability, and precision, while lowering operating costs with the introduction of innovative components, unique capabilities, and optimum flexibility. The new SPECTRO ARCOS establishes a new ICP-OES performance class for complex analytical tasks − resolving a wide array of inherent problems in traditional spectrometer design − and caps 30 years of SPECTO experience in developing advanced solutions for the elemental analysis of metals, chemicals, petrochemicals and other materials. Features of the new SPECTRO ARCOS include: • Axial or radial plasma observation • ORCA optical system • Innovative power generator • Elimination of the need for purge gases • No external cooling system Enquiries: Email spectro.info@ametek.com
