Standard Smoke Tunnel – Factory Version
Equipment Function：
Standard smoke box is used to test the sensitivity, directionality, repeatability, high and low temperature, dazzling and other characteristics of smoke alarm. The equipment meets the requirements of GB 20517, GB4715, EN 14604, EN 54-7 and ISO standards. Standard test tunnel is composed of smoke tunnel, photoelectric smoke density meter, heater, chiller, small scale dazzling device, computer, etc., and has high quality optical obscuration meter used to measure the smoke concentration value in the smoke tunnel. The equipment has the function of constant smoke control, which can automatically control the smoke concentration in the box in the setting obs. Wind speed, smoke rate and temperature are settable in software to meet standard test requirements. The specially developed Zontest Smoke Test Tunnel software continuously monitors the Smoke concentration, Smoke rising speed and temperature, and records the alarm sensitivity. continuously monitors Smoke.
