A Photon Wrangler's Phriend

SolarSeanERockett

A robust, hand-held, diagnostic instrument with more features than most PV technicians will need. More than sufficient for PV field engineers conducting myriad types of work at photovoltaic (PV) electric power generation facilities. Looking forward to digging into the more advanced features and the blue-tooth is nice for working in high-hazard limited and restricted arc-flash boundaries. Safety first; Safety works.
