The instrument features a central needle, topped by a precise graduation ranging from -15 to +15 amperes, with a clearly legible \"AMPERES\" marking in black capital letters at the top.\u003c\/p\u003e\n\n\u003cp\u003eThe dial also displays the words \"PRECISION\" and the brand \"MB\" in straight characters, located below the needle's axis. The fine and regular graduation, with indexing every ampere, indicates professional or laboratory use. The center of the dial reveals a central screw and two visible metal contacts, typical of electrotechnical measuring devices from the first half of the 20th century.\u003c\/p\u003e\n\n\u003cp\u003eThe metal rim, with a bronzed and oxidized appearance in places, shows traces of wear and chipping, confirming the device's age. The curved, slightly cloudy glass protects the dial and needle. No other elements are visible on the front face, which highlights the clean and functional style of this type of instrumentation.\u003c\/p\u003e\n\n\u003cp\u003eThe visible part does not include any other inscriptions, buttons, or decorations. The whole evokes the manufacturing standards of electrical measuring devices used in workshops, laboratories, or industrial facilities in the mid-20th century, with a sober and utilitarian aesthetic.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eCondition\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eUsed device, sold as is.
