Once the lineup cards are submitted (approx. 5 minutes before game time), the umpires take control of the field and the crew chief becomes the person who decides whether to delay or postpone a game (and if/when to restart).
A firewood moisture meter can be used to determine the moisture content of your firewood, but are they a necessity or just a novelty? Seasoned firewood is considered to have a moisture content of 20% or less.
Electric (dielectric or conductivity) Moisture content is determined by measuring the change in capacitance or resistance to an electric current passed through a sample. Hydrometry Used to determine moisture/ solid content of beverages and sugar solutions. Measuring the specific gravity or density of the sample via one of the following instruments: Pycnometer: used to compare the weights of equal volumes of a liquid and water. Yields density of the liquid compared to water.
