Laboratory-scale To ensure that products meet federal and industry regulations, the moisture content is measured using halogen or other infrared heaters. Like any different exact analytical scale or balance, a moisture analyzer must be accurate to function correctly. To ensure the accuracy of moisture analyzers, two independent calibration processes must be completed: one to ensure temperature and another to ensure weight. If you want to know how to calibrate your moisture balance accurately, keep reading!
Why Do Moisture Analyzers Need to Be Calibrated?
Only a few interruptions may substantially impact the overall accuracy of a moisture balance. The gravitational pull in various locations of the globe necessitates that newly acquired analyzers be calibrated on the spot before they can be utilized. When moisture analyzers are being utilized in the lab or at a different location, even if it's only in a new place of work, changes in ambient conditions might impact accuracy. The workspace should be adequately soundproofed and heated or cooled to prevent noise and temperature fluctuations brought on by moving carts over the floor.
It is necessary to calibrate the weighing system
It is necessary to do external calibration on moisture analyzers to be as accurate as possible. These adjustments are made by combining a particular moisture balance test with predetermined adjustment weights like 50 grammes. The operating instructions accompanying the devices provide information on how to calibrate different models of moisture analyzers. The calibration weight is placed on the sample pan once the device has been set to suit the importance of the pan. For example, if the moisture analyzer shows an incorrect number for the real weight, the analyzer will automatically correct itself, and the exercise will be completed without additional input.
Temperature Testing And Determination
Heating systems may be calibrated using temperature calibration kits, which can be purchased separately. However, your moisture analyzer must be cooled down for three hours before any tests can be carried out. Insert the temperature probe as close to the sensor as possible, following the instructions in the instruction manual.
In comparison to the weight calibration technique, the temperature checks are more time consuming and require the use of two independent pounds. A moisture balance can only offer accurate findings if it is calibrated regularly in your laboratory. All laboratory employees must be aware of the calibration procedure and its timeframes.
