- Moisture content— AKA water content— is a measurement of the total amount of water contained in a food, usually expressed as a percentage of the total weight (see calculation). It’s a useful measurement for determining the dry weight of your food and ingredients and it helps calculate your total yield.

However, to get the best testing results, it’s important to understand moisture meter readings—how they work, what impacts test results, what the different moisture reading scales mean, and how to ensure the most accurate results possible.
Find out which reading is considered normal on a moisture meter. Learn what is the normal moisture value on different materials and surfaces.
Jun 17, 2021 · Moisture Meter Readings: The Tools of the Trade. Taking and interpreting moisture measurements accurately starts with understanding how a moisture meter works. There are two types of meters used in moisture surveys: pinless and pin-type meters. Pinless Moisture Meters.
- The Reference Scale. The reference scale is quite different from most other moisture measurement scales. Most reading scales are designed to provide a specific, quantitative measurement of moisture content (%MC) in a given type of material.
- The Wood Scale. The wood scale is, as the name implies, optimized for getting precise %MC measurements in wood materials. This scale is often used in the flooring, construction, lumber, and restoration industries.
- The Drywall Scale. With most moisture meters, drywall is measured using the reference scale and comparisons to dry materials. However, Delmhorst offers several moisture meters that are calibrated specifically for drywall.
- Hay Scale. Hay moisture meters work by providing a percentage-based moisture content measurement of moisture in hay. These meters typically work best when measuring a haystack or bale because the hay will be more tightly packed.
A high-quality moisture meter used on the right material can be accurate to within less than 0.1% of the material’s moisture content by weight. However, a low-end moisture meter can be wildly inaccurate.
Moisture content is simple in theory – but in reality, it's almost impossible to obtain an accurate, repeatable MC measurement. Here’s why. Water activity, which provides information about product safety and quality, is often thought to be a more complicated measurement than moisture content.
