Moisture analyzers determine the moisture content of relatively small samples of various materials. The PMR ranges from 50g to 210g.
Moisture analyzers make use of "Thermogravimetry", which is a process in which the decrease in mass is determined when a substance is heated. In this process, a sample is weighed before during and after drying process, and a difference in mass due to the loss of moisture is calculated.

The humidity of a substance is a composition of all components which appear in a sample, and which evaporate during heating. The products released during drying may include grease, aromatic substances, organic solvents, chemical additions, water and other components.

Choosing a moisture analyzer
If the moisture analyzer is to perform drying procedures only, then a 50g capacity instrument is sufficient. Determination of moisture content requires relatively small samples. The standard temperature range, up to a maximum of 160°C, is sufficient for 95% of applications. However, if samples have to be dried in very high temperatures, a halogen lamp heater up to 250°C is available.

Infrared emitters emit longer waves, but less energy. With the increase of wavelength, the reflection ratio decreases. This means that more energy is absorbed by the substance (up to 80 %) rather than reflected from its surface. Such waves are applicable for substances that have high reflection ratio, and substances with dark colour.
