The moisture content of cannabis is measured with a moisture meter that is an essential electronic instrument used in many industries to detect moisture content in foods and other items like wood and vegetation. Most moisture meters are calibrated and provides accurate reading. Typically, in cannabis moisture content readings should be below 15% when the product is in market.
Residual solvents are leftover chemicals from the process used to extract cannabinoids and terpenes from the cannabis plant. The solvents are evaporated to prepare high-concentration oils and waxes. Sometimes, the evaporation process does not remove all of the solvent. Since these solvents are not safe for human consumption, it is important to verify their absence so you can guarantee you are providing a safe, chemical-free product.
Water Activity Testing is a Regulations Test in California. Measuring the water activity in a cannabis product is an excellent way to test how susceptible the product is to microbial contamination. The higher the measured water activity is in a product, the more freely water can be used by microbes as a food source or to support chemical and enzymatic reactions leading to spoilage.
In other words, the higher the water activity value, the more vulnerable cannabis products are to microorganism growth.
