For drift-free air flow measurements across traffic tunnels; WSS-300 calculates true average speed of air movement, and detects smoke. Equipped with Automatic Gain Control (AGC) to compensate for opacity variations caused by particulates, smoke, or suspended moisture, the WSS-300 uses patented optical scintillation technology coupled with advanced Digital Signal Processing (DSP) electronics to "see" and deliver highly accurate, path-averaged air flow measurements superior to anything on the market today.
