Project Description

Equipment Function：

The smoke alarm test tunnel was designed for sensitivity test of Smoke alarm or Heat detector according to GB 20517、GB4715、EN 14604、EN 54-7 and ISO standards. It consist of test tunnel，aerosol generator, obscuration sensor, heat element, controller and computer. The obscuration meter was made of high quality imported part to ensure precision and stable reading. The Zomtest Smoke Test Tunnel Software in English was designed by our software expert specifically to meet the standards test requirements.
