Hioki’s solar HiTester 3245-60 is an environmentally friendly digital multimeter. The hybrid power system incorporates both a main rechargeable lithium-ion battery powered by solar source with eight hours of use available on three hours of charging at 50,000 lx and a backup battery. It has pocket-sized CAT III (600V) and CAT IV (300V) conformance (when test pin sleeves are attached), and test probes are stored in the back.
