Abstract

An electronic balance including a housing (1), a weighing scale (2), a windshield (3), which preferably at least partially surrounds the weighing scale, and a display and operating unit (4) which is connected to the balance housing. The connecting part (5) between the display and operating unit (4) and the housing (1) consists essentially of a material with poor heat conduction properties. At least one vertical radiation protection plate (6) is provided between the display and operating unit (4) and the housing (1), and the connecting part (5) is configured in such a way as to impair air convection on both sides of the radiation protection plate(s) (6) preferably to the least extent possible. This results in excellent thermal decoupling between the display and operating unit (4) and the housing (1).
