Which tool provides site-specific wind, temperature, and humidity information?

• A. Weather vane
• B. Anemometer
• C. Weather meter
• D. Hygrometer

Answer: (C)

The concept being tested is using a tool that provides on-site measurements of wind, temperature, and humidity. Getting data right at the application site matters because drift risk and pesticide effectiveness depend on current conditions.

A weather meter gives all three readings in one handheld device: wind speed, wind direction, temperature, and humidity. This on-site, real-time data helps you decide if conditions are suitable for spraying and whether to adjust operations accordingly.

Wind vane only shows which way the wind is blowing, not speed or other conditions. Anemometer measures wind speed alone. Hygrometer measures humidity alone. None of these provide the full set of site-specific information you need, whereas the weather meter does.
