Serum ferritin levels are considered the best indicator of iron stores in the body. Ferritin is a protein that stores iron, so measuring its levels in the blood can provide valuable information about the body's iron status.

The sun is considered the best timekeeper because it rises and sets at predictable intervals every day, creating a consistent and reliable cycle of day and night. Its movements can be used to track time accurately and it has been a natural time indicator for centuries, influencing how humans measure time.
A weather station is the best device to measure atmospheric pressure, temperature, and moisture. It typically includes instruments such as a barometer for pressure, a thermometer for temperature, and a hygrometer for moisture measurement. These devices provide comprehensive data for monitoring weather conditions.

on my altimeter the altitude will be reported as going down if the weather is improving, which means that the pressure is actually going up, and the inverse is true also. Not sure if that answers your question, but its the relative differences which makes more sense in the field rather than exac numbers. If I see a jump in altitude of about 200m I know bad weather is coming, and if Im looking out wondering I know the weather is improving if the altitude goes down.

Universal indicator is the best choice because it can indicate a broad range of pH values accurately, from acidic to alkaline solutions. This makes it suitable for a wide range of experiments involving pH variations. Additionally, universal indicator changes color based on the specific pH of the solution, allowing for easy and precise determination of the solution's acidity or alkalinity.
The atmospheric pressure is the best indicator of current and changing weather conditions, because low pressure will indicate clouds and storms coming. High pressure indicates that clear skies and sunny weather are to come.
