Summary:To provide a test device which can easily perform a test of a differential distribution type sensor.SOLUTION: A test device 1, for performing a test of a differential distribution type sensor 10 which senses a fire by detecting pressure rise in an air pipe 11 laid in a warning area by a diaphragm 14 that communicates with the air pipe 11 via an air pipe connection part (cock stand 13) connected with the air pipe, comprises: air injection means (test pump 4) which injects the air into the air pipe; a pressure sensor 2 which is provided between the air pipe and the air pipe connection part and detects the pressure in the air pipe; and a determination processing unit 3 which determines the test result of the differential distribution type sensor on the basis of the output value of the pressure sensor.SELECTED DRAWING: Figure 1 【課題】差動式分布型感知器の試験を簡単に行う試験装置を提供する。【解決手段】警戒区域に敷設される空気管１１内の圧力上昇を、空気管１１とそれが接続される空気管接続部（コックススタンド１３）を介して連通するダイヤフラム１４によって検知して火災を感知する差動式分布型感知器１０の試験を行う試験装置１であって、空気管内に空気を注入する空気注入手段（テストポンプ４）と、空気管と空気管接続部の間に設けられ、空気管内の圧力を検知する圧力センサ２と、圧力センサの出力値に基づいて、差動式分布型感知器の試験結果を判定する判定処理部３と、を備える。【選択図】図１
