Development of Response Time Tester

Article Preview

Abstract:

In order to solve the difficult problem of the transmission-type smoke meter response time, which needs to be settled urgently, response time testers have been developed, according to China's metrological verification regulation JJG 976-2010《Calibration procedures of transmission-type smoke meter》. The tester integrated several communication protocols of transmission-type smoke meter manufacturers, takes measurements at every 20ms, draws absorptance N curves in real time and displays the final response time in man-machine interface. The measuring range of the tester is (600~2000) ms, and the error is ±20ms. It is very convenient, fast, and accurate to verify for transmission–type smoke meter and traffic analyzer.
