Overview

The CRYSTAL THERM Model Moisture Control Analyzer Balance can determine the weight in milligrams with a maximum capacity of 200 grams and a resolution of 1 milligram. That allows a measure of extreme precision during the development of discovery. (When more decimals are indicated, the smaller the possible weight, to comparable accuracy).

The scales for measuring humidity have been designed for use in the industrial and professional sectors. Its main function of analyzer moisture is to determine the dry substance that remains after a drying process of the total heavy substance beforehand and thus calculates the moisture of the heavy wet mass.

What is a desiccator?

Desiccators are sometimes called “moisture analyzers”. These are instruments that determine the moisture content of various types of samples. Drying procedures are highly customizable because different samples react to different drying procedures differently. Desiccators are often connected to computers to observe and analyze the heating procedure and its effects on sampling. You can save the tests in the instrument’s memory to repeat the frequent test settings without having to constantly reprogram them, which saves a lot of time.

How does it work?

Essentially, the dryer weighs samples, heats it to dehydrate and weighs it once the sample is dry. It is also called loss on drying, loss on drying or loss by dehydration. This is a standard method for measuring moisture. The sample is weighed, dried and weighed again. The weight after the desiccation is subtracted from the weight of before, so the loss of water is determined using the loss of mass.

here are several types of desiccators, and they use various means to generate heat. Our PMB uses a 400 watt halogen bulb that heats the sample in selectable increments of 1 ° C. Halogen bulbs are fast, efficient and responsive, making them ideal for moisture analysis because there is no parameter that works for all samples; some must be dried with constant heat while others must be dried using special increments to avoid damaging them.

Here’s how it works: Start the dryer, choose or adjust the test settings, put a sample in a cup and close the lid to begin the drying process. The analysis happens during the drying of the sample. It ends either when the test is finished, or after a period of time predetermined by the user. Data is often sent to a computer or saved in a USB drive for in-depth analysis and observation. Reports are compliant with ISO and GLP standards.

Drying mode

Increasing Temperature: The temperature rises to a specific degree for a predetermined period of time. For example, 125ºC in 10 minutes.

Alone: ​​A unique temperature. The dryer will heat up to a specific temperature and hold it for the duration of the test, regardless of the length.

Echelon: Heats at one temperature for a programmed period of time and then at another temperature for another period of time. There is a maximum of 3 settings in the PMB. So you can set it for 100ºC for 3 minutes, 125ºC for 2 minutes and 150ºC for 6 minutes.

What are the applications?

Designers are used in a variety of industries for various applications. Here are the most common:

Agribusiness: moisture analysis is very important in the food industry. Too much moisture can lead to stale foods or bacteria growth. Many foods are sold by weight, so it is important to be sure that customers do not pay a surplus because of the weight of the water. Too little moisture can reduce the caloric count or make the food dry. Laboratories frequently use desiccators for quality control and material testing. Moisture analysis is used in various industries to determine the amount of water in crude oil, fuel, sewage sludge and many other chemicals, both liquid and solid.
