What is the principle of moisture analysis?
The principle of the thermogravimetric method of moisture content determination is defined as the weight loss of mass that occurs as the material is heated. The sample weight is taken prior to heating and again after reaching a steady-state mass subsequent to drying.
What is moisture analyzer function?
A moisture analyzer determines the moisture content of a sample with the loss on drying method and consists of a weighing and heating unit (infrared). It is often also called moisture balance or moisture meter.
What is the purpose of moisture content?
Moisture content of the food material is important to consider the food is suitable before the consumption, because moisture content affects the physical, chemical aspects of food which relates with the freshness and stability for the storage of the food for a long period of time and the moisture content determine the …
What is IR moisture analyzer?
What exactly is an infrared moisture analyzer? The equipment determines moisture of a sample by heating and drying it with infrared irradiation and displays the moisture content measured from changes in mass due to evaporation.
How do you check moisture balance?
Moisture Determination Balances provide a primary method for accurate moisture measurement by using the loss on drying (LOD) method. A liquid or solid sample is placed in the sample pan. The integrated balance weighs the initial sample. The balance’s lid is closed, start button pressed, and the sample is dried.
What are the types of moisture?
Generally, an aggregate has four different moisture conditions. They are Oven-dry (OD), Air-dry (AD), Saturated surface dry (SSD) and damp (or wet).
How does an infrared moisture analyzer measure moisture?
Definition An infrared moisture analyzer is an instrument that substitutes a loss on drying method used for many official analytical methods for moisture determination. The equipment determines moisture of a sample by heating and drying it with infrared irradiation and displays the moisture content measured from changes in mass due to evaporation.
How does a halogen moisture analyzer measure moisture?
The Halogen Moisture Analyzer works according to the thermo-gravimetric principle, also often referred to as ‘Loss on Drying’ (LOD) principle. The moisture analyzer consists of two components, a balance unit and a heating unit. In order to measure the moisture content the sample’s start weight is recorded,…
Why do you need a moisture analyzer in your home?
It consists of a weighing unit and a heating unit (infrared technology) and is used to determine the moisture content of a sample with the loss on drying principle. Today many customers use a moisture analyzer because they want to analyze moisture content using the fast and easy loss on drying method.
How does a moisture analyzer like tovatech work?
Moisture analyzers such as the models offered by Tovatech operate on what is called the thermogravimetric method, a fancy word meaning loss of weight on (heated) drying, abbreviated as LOD. Simply stated, they calculate the before and after weight with the difference denoting the sample’s moisture content.
