A weighing system (10) is provided with a work space (3) in which a weighing device (5) can be installed; a containment device (13) that blocks everything except an opening (134), an air inlet (132), and an air outlet (133) and defines the work space (3); a temperature and humidity control device (11); a filter unit (12); and a first connection means (14), second connection means (15), and third connection means (16) for connecting the above. As a result, air having a controlled temperature and humidity circulates through the weighing system (10), there is laminar flow in the work space (3), and powder floating in the work space (3) is securely contained in the weighing system (10).</p> |
