<p><P>PROBLEM TO BE SOLVED: To provide a culture device for controlling gas concentration, using an infrared gas concentration detector, and allowing temperature elevation to a high temperature without removing the gas concentration detector. Ž<P>SOLUTION: The gas concentration detector 12 is inserted and attached to a through hole 22a, provided in a wall part 22 of an environment control chamber 10, in the culture device 1. A light source 30 and a detection part 31 are provided in the gas concentration detector 12, gas in the environment control chamber 10 flowing into an in-vessel gas passing hole 27 flows into an intersection part 35, and the intensity of infrared rays, emitted from the light source and passed through the intersection part, are measured by the detecting part to detect the gas concentration. The detecting part 31 is arranged in an outward projection part 41 projected more outward than the wall part 22. Ž<P>COPYRIGHT: (C)2006,JPO&NCIPI Ž</p> |
