Improve your production with NIR moisture analyzing technology

In some instances, your products may fail to meet the intended quality levels or specifications needed by the customer. In such scenarios, the cause of the problem can be improper moisture measurement and control. However, the NIR moisture analyzer can assist in the accurate measurement of the moisture content of your raw materials to ensure that you produce quality products through your efforts.
LOD vs. NIR moisture meters
NIR moisture measurement is one of the many technologies used for measuring the moisture levels. The other common method that can be used is the Loss on Drying (LOD). Below are highlights of each of the methods.
LOD 
Loss on drying method works by weighing a sample before drying and weighing it again after it has dried up. The difference between the dry weight and the original weight (wet base test) is considered to be the weight of the moisture content in the product. The tests are either done manually or through the use of automated machines.
NIR 
NIR (Near Infrared) is a meter test method designed to mitigate the shortcomings of the LOD method. Notably, NIR is a secondary measurement method where the instrument is calibrated to give the true moisture measurement.
NIR analyzer makes use of infrared light directed on the product under test. Some of the light is absorbed while some is reflected. The ratio of absorbed light to reflected light provides grounds for comparison between different materials contained in the sample. This test can be used to measure the concentrations of different ingredients in the material. You should note that this light does not harm the product or the user.
The advantage of the NIR method is that it provides instantaneous results. The test is also not destructive, and it is also non-contact. Additionally, you can use the technology to measure the moisture content of any solid and any liquid.
If you reside in remote areas, you can use battery-powered units for testing. This unit can also be used for surface moisture measuring to optimize drying, curing and packaging. The technology can also be used to measure wavelengths of several organic concentrations such as sugar, oil, and fat.
To ensure that you get the right results, the instrument will require calibration at the start of the measurement which varies depending on your location. Unfortunately, the instrument only measures the moisture of the surface of the product hence the relationship between the surface moisture and the total moisture levels has to be established.
Before purchasing the NIR moisture analyzer, it is important to determine the characteristics that you want to measure and their impact on the overall product quality. You can do this by going through the quality control logs and other quality measures that you have in place. If moisture or organic matter concentration is significantly affecting the quality of the product, the NIR moisture analyzer will be of great advantage. Such an investment with brings good ROIs on your business.
