FLUKE 87V MAX Digital Multimeter and PVLEAD1 Test Leads Kit is an ideal electrical troubleshooting solution for solar inverters, combiner boxes, and battery storage systems. The 87V MAX is built with an IP67-rated, industrial-strength case and a removable holster. For a more manageable, one-handed operation, the holster doubles as a test probe holder. This meter is fully waterproof/dustproof and keeps working reliably regardless of the job. Safely connect the PVLEAD1 solar MC4 test leads to the meter to validate voltage from individual panels or a series of panels in a PV array.
