The Gossen Metrawatt METRALINE CM 400 is a robust, compact TRMS clamp meter for versatile use in the electrical trade, in industry, in electromobility and in photovoltaic systems. The 35 mm oval clamp opening enables convenient current measurements on cables and rails, while the CAT IV / 1000 V measurement category ensures maximum safety when working on AC and DC applications. Practical functions such as non-contact voltage testing (NCV), low-pass filter (LPF) for frequency-influenced measuring points, min/max detection, hold, display and flashlight illumination as well as automatic switch-off ensure efficient and safe everyday work.
Application areas: Installation, maintenance, troubleshooting, e-mobility charging infrastructure, switch cabinet construction, PV strings, machine and system service.
The METRALINE CM 400 combines a handy design with an easy-to-read, illuminated 4000-count display and a handy rotary switch for quick selection of the measurement mode. The shock-resistant design, TRMS measurement and extensive test and measurement functions make it a reliable companion on any construction site and in service.
