Abstract: Provided is a protective cover for a weighing instrument in which movement of a sliding door does not degrade over time. A protective cover (2) for a weighing instrument includes sliding doors (2L, 2R) defining a weighing chamber (5), an upper frame (11) formed at an upper edge of the sliding door, a lower frame (12) formed at a lower edge of the sliding door, an upper guide rail (17) disposed on the upper frame, and a lower guide rail (18) disposed under the lower frame, where the upper guide rail suspends the upper frame, and between the upper guide rail and the upper frame, balls (215) are disposed at a plurality of positions in a moving direction of the sliding door.

Abstract: Provided is an animal weighing scale that automatically measures a weight of an animal by a simple configuration. The animal weighing scale includes a breeding container for laboratory animals and a scale including a weighing pan supported by a weight sensor, the weighing pan is disposed inside a breeding space of the breeding container, and the weight sensor is disposed inside or outside the breeding space, and accordingly, based on a measurement value change when an animal inside the container is placed onto the pan, a weight change of the animal can be continuously recorded.

Abstract: Provided is a measuring system capable of stably, safely, and easily measuring hazardous fine particles. A measuring system 10 includes a work space 3 in which measuring equipment 5 can be installed, a containment device 13 that defines the work space 3 by closing portions other than an open section 134 and an air inlet 132 and an air outlet 133, a temperature and humidity control device 11, a filter unit 12, and a first connection means 14, a second connection means 15, and a third connection means 16 that connect the above-described components. Accordingly, in the measuring system 10, air whose temperature and humidity are controlled circulates, and a laminar flow flows in the work space 3, and particles floating in the work space 3 are reliably contained inside the measuring system 10.
