Easy to use, the MTX 3283 multimeter from the MTX Mobile product family provides direct single-handed access to its functions, thanks to an electronic measurement switch. Equipped with a large multidirectional LCD screen, it has four 100,000-count digital displays and English/French bilingual menus.
In order to optimise efficiency and safety during use, the "Ampere" and "Volt" measurement terminals allow automatic selection of the appropriate function, in AC+DC mode, and default automatic range.
The MTX 3283 communicates in all environments thanks to its RS232 and optical USB ports, and its Bluetooth technology.
