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.

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
