I am interested in the temperature speed sensor anemometer wind speed meter. I intend to use it for measuring the wind speed of exhaust air from a cooling tower. The exhaust air is not pure; it may contain dust, water vapor, and traces of chemical water treatment. The sensor would be installed in a horizontal orientation. Confirm whether the product is suitable for this type of application. Provide detailed product specifications, including materials used, protection rating, operating temperature and humidity range, output signal type.
