4. Scientific probe.
Explanation:
1. <em><u>Scientific probe</u></em>: measures a variety of data, including pH levels and conductivity. Thus, a scientific probe is a device that is typically used for measuring science-based data such as electrical conductivity, pH levels, salinity etc., of various materials.
2. <em><u>Weather station</u></em>: measures temperature, humidity, wind speed, and pressure. Basically, a weather station comprises of various devices for measuring atmospheric conditions such as thermometers, barometers, hygrometer, wind vane etc., used for the measurement of temperature, atmospheric pressure, relative humidity and wind speed respectively.
3. <em><u>Weather station</u></em>: gathers information about local atmospheric conditions.
4. <em><u>Scientific probe</u></em>: can digitally record data, such as flow rate.
