Moisture analyzers are required to detect the presence and quantity of water in a sample. For example, oil and gas with a higher moisture content are lower quality and may damage equipment. Because of these results, detecting a higher moisture content reduces the price point of products as well. In the food industry, moisture analyzers are key to assessing the quality of incoming ingredients. Learn more at LabManager.com/moisture-analyzers

5 Questions to Ask When Buying a Moisture Analyzer:

  1. What material or product is being analyzed for moisture content?
  2. Are the samples sensitive? Some means of moisture analysis can damage materials. Opt for moisture analyzers that utilize capacitive- or microwave-based moisture detection for sensitive products or materials.
  3. What is the typical sample size? For most testing purposes, 3-5g is a good sample size.
  4. What additional features and benefits does a specific moisture analyzer offer?
  5. How many samples do you need to run in a given time period?

Maintenance Tip

Ensure you have a schedule for maintenance of your moisture analyzer right from the date of purchase. The schedule should include looking over all parts (including hoses, electrodes, etc.) of the moisture analyzer for wear and possible damage. Spills can permanently stain and damage a moisture analyzer, so you should have a cleaning schedule to clean any residual reagents or chemicals that may have been spilled in or on the moisture analyzer. 

Usage Tip

To accurately measure the moisture content of samples, the moisture analyzer must be kept under specific conditions. For example, the temperatures of the sample itself and the room can significantly affect the moisture analysis results. Storage in a damp environment can reduce the accuracy of the moisture analyzer, and drastically impact results. Even exposure to sunlight can reduce the reliability of your results. Carefully read and follow manufacturer guidelines that come with your machine to ensure storage and usage of the analyzer are within acceptable ranges.
