MEASURING SYSTEM

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.

Claims

1-4. (canceled)

5. A measuring system comprising: a work space in which measuring equipment can be installed; a containment device that defines the work space by closing portions other than an open section provided in the front surface of the work space, and an air inlet and an air outlet set in the work space; a temperature and humidity control device that controls a temperature and a humidity of taken-in air and can blow the air into the work space; a filter unit that collects particles; a first connection means that hermetically connects the temperature and humidity control device and the air inlet of the containment device; a second connection means that hermetically connects the air outlet of the containment device and the filter unit; and a third connection means that hermetically connects the filter unit and the temperature and humidity control device, wherein an upper horizontal baffle that has a vent hole and controls an airflow is provided at an upper position in the work space, the air inlet of the containment device is provided on an upper surface of the containment device, and the air outlet is provided at a position substantially central in the device front-rear direction and the device up-down direction of either of the left and right side surfaces of the containment device in the work space lower than the upper horizontal baffle.

6. The measuring system according to claim 5, wherein the vent hole is formed at a position except for a region below the air inlet of the containment device.
