Loop / PFC Testers
PeakTech Prüf- und Messtechnik GmbH
The PeakTech 2715 is a loop tester which is used to test the safety of electrical systems. These device measures the impedance of the short-circuit loop between the outer conductors of a circuit, whereby the probable short-circuit current is calculated. The protection of the circuit (miniature circuit breaker) must therefore trigger at a lower current than the expected short-circuit current, in order to avoid excessive heating of the lines and thus a fire risk. The PeakTech 2715 is due to its function and its robust design almost indispensable when performing new installations, but also for general checking of electrical systems, this device is the ideal companion.

General Purpose Benchtop XRD System for Phase I.D. and Phase Quantification
In a move to bring lab-quality performance to the manufacturing floor, Rigaku introduces the MiniFlex XpC, a manufacturing-optimized powder diffractometer for fast and accurate quality control measurements. It is extremely easy to operate using Rigaku’s new EasyX quality control software, which requires minimal clicks to run. A minimal interface means there will be no accidental error variance from operator to operator. The MiniFlex XpC can be configured with a conveyor belt or robot for automated sample processing and collaboration with other instruments. With an 800 W X-ray source and a short-diameter goniometer, the system has the performance of a lab unit, and thus can greatly improve throughput for quality control measurements.
