What is a moisture analyser?
Moisture analysers are specialist digital devices used to determine the moisture content in organic samples. They typically employ an LOD (loss-on-drying) method using a halogen heating bulb to dry samples, the moisture lost from the sample is then used to calculate the total moisture content of the sample as a percentage prior to drying.
How do moisture analysers work?
This will depend on the type of moisture analyser you are using. Halogen moisture analysers have a built-in halogen bulb that is used to heat and dry samples over a pre-defined length of time. After heating, the moisture analyser will show the percentage value of moisture loss from the sample.
What are moisture analysers used for?
Moisture analysers are typically used in agricultural and food testing laboratories for detecting the moisture content within fertilisers, grain, crops and grocery products, such as biscuits and cereals to ensure optimum moisture content. Too much moisture can cause premature bacteria growth in food products, whilst too little will affect the overall consistency and product quality.
Moisture analysers can also be used to measure the consistency of oils, creams and water-based cosmetic products by accurately extracting a water content value and comparing the amount of water to ingredients as a ratio.
