The Fluke 393 FC real effective current clamp with measurement category CAT III 1,500 V was developed for technicians who work in high voltage DC environments: PV systems, wind energy, electrical railways and uninterruptible power supply for data center. It measures up to 1,500 V DC, 1,000 V AC, and up to 999.9 A DC/AC using the clamp. The accompanying flexible current sensor iFlex extends AC measurements up to 2,500 A. The measuring device has a slim wrench, which enables you to access cables in narrow connection boxes. The measuring leads were developed for work up to 1500 V DC and are specified in accordance with CAT III 1,500 V.The Fluke IRR1-SOL irradiation measurement device was developed to simplify the installation, start-up and troubleshooting of photovoltaic systems and to enable the measurement of solar radiation, temperature, inclination and alignment with a single handheld device. The IRR1-SOL can be used anywhere thanks to its robust, compact design, a protective carrying
