摘要

A wind shield (3) surrounds a weighing area (6) where a scalepan (2) is positioned on a base of weighing scale housing. A vertical air flow tube with a small cross-section for upwardly-directed air flow, is connected to weighing area. A ventilator is arranged inside the tube. A Peltier element is connected to tube lower end and scale base, and a heat resistor (11) is connected to rear wall (8) of housing.
