The invention relates to the field of gas sensitive material test, and provides a multi-channel film-type gas sensitive material response test device. The device comprises a gas test chamber, a sealing ring, a sample cell cover plate and a plurality of pairs of metal electrode poles, the sealing ring is arranged between the gas test chamber and the sample cell cover plate, through holes are arranged in the sample cell cover plate, and the metal electrode bars penetrate the through holes to be fixedly connected with the sample cell cover plate. Direct insert type electrodes are adopted, current loss can be reduced, response signals are captured conveniently, and the device has high sensitivity and small measurement error. 本发明涉及气敏材料测试领域，提供种多通道薄膜型气敏材料响应测试装置，该装置包括气体测试腔体、密封圈、样品池盖板和若干对金属电极杆，密封圈设置在气体测试腔体和样品池盖板之间，样品池盖板上设置有通孔，金属电极杆穿过通孔并与样品池盖板固定连接。本发明提出的技术方案采用直插式电极，能够减少电流的损失，便于捕捉响应信号，具有较高的灵敏度和较小的测量误差。
