Industrial Analyzers: What Are Moisture Analyzers

in Moisture

In the power generation industry, moisture analyzers are important as they serve as moisture meters of water vapor. Most companies that make use of the analyzers are those that are interested in measuring the moisture content but need the result much quicker. Other companies also rely on these to test a particular sample for the first time.  In some industries, such as food or pharmaceutical, these analyzers are responsible for quality control of products to ensure that the moisture in the products would not affect the shelf life as well as prevent any unsavory negative reactions when the products enters their final phase.

What is a Moisture Analyzer?

Moisture analyzers are often used when companies employ infrared heating technology to perform Loss on Drying” or LOD method. When a product is heated, it loses moisture, thus losing weight in the process. The initial weight of the sample is ten compared to the final sample product weight.  Analyzers of these types have two important components – heater and a balancer. The balancer weighs the sample’s initial weight. Once the initial weight is obtained, the sample will be placed in the heater where the process of removing the moisture starts. When the sample is deemed to have lost its entire moisture content, the heater will automatically shut off and the final weight is calculated.

Modern Analyzers

Most of the moisture analyzers today are programmable and set to accommodate different samples or substances although they are a bit expensive than most standard model. However, the fact that the analyzers are programmable makes them a value for money for industrial companies that manufacture several products.

 To successfully maximize the analyzer, one must be familiar with the steps to ensure accurate readings especially if there are several products to be analyze. Most start with establishing a certain procedure for each product to be sampled. The next step is to take the sample plate and place it in the balance to record the initial weight. After obtaining the initial weight, the samples are spread out in the plate to start the heating process. When the sample loses all its moisture, the heater will automatically stop and once the dry weight becomes stable, the person manning the analyzer can now record the difference between the two weights obtained.

For those who are interested in purchasing their own moisture analyzer, it is best to contact or talk with a specialist especially when it comes to the power generation industry.
