Accurate moisture measurement is fundamental to quality control across manufacturing, research, and production environments. Whether you’re ensuring pharmaceutical compliance, optimizing food production, or maintaining agricultural product standards, a reliable moisture analyser delivers the precision and speed your operations demand.
The Intelligent Moisture Analysis That Works as Hard as You Do

A moisture analyser is a precision instrument designed to measure the moisture content in various materials quickly and accurately. It works using the thermogravimetric method, where a sample is heated using a halogen lamp or infrared heat source, causing the moisture to evaporate. The instrument continuously measures the weight loss during this heating process and calculates the moisture content as a percentage of the original sample weight. Advanced models like the M Series feature halogen lamps with SRA (Secondary Radiation Assist) filters that provide fast, uniform heating for shorter measurement times and more reliable results.
Moisture analysers are essential across numerous industries including pharmaceuticals, food and beverage production, agriculture, chemicals, plastics manufacturing, and research laboratories. They’re used wherever precise moisture measurement is critical for quality control, compliance with regulations, or process optimization. In pharmaceutical manufacturing, they ensure medications meet strict moisture specifications. Food producers use them to maintain product consistency and shelf life. Agricultural businesses rely on them to assess grain and crop quality.
Accurate moisture measurement is crucial for product quality, safety, and profitability. Excess moisture can lead to microbial growth, reduced shelf life, and product degradation. Insufficient moisture can affect texture, taste, and processing characteristics. In manufacturing, incorrect moisture levels can cause production issues, waste, and non-compliance with industry standards. Financial implications are significant too – since moisture adds weight but not value, accurately measuring it ensures you’re paying for product, not water.
Halogen moisture analysers offer several key advantages over traditional drying ovens. They provide rapid results, often completing measurements in minutes rather than hours. The halogen heating technology delivers uniform, controlled heat distribution for consistent, reproducible results. They require minimal sample preparation and smaller sample sizes, reducing material waste. The M Series specifically uses SRA filter technology for enhanced heating efficiency. These instruments also eliminate operator subjectivity with automated measurements and digital displays, improving accuracy and reducing human error.
Selecting the right moisture analyser depends on several factors. Consider your sample types and their temperature sensitivity – some materials require gentler heating profiles. Evaluate the required accuracy and readability, typically ranging from 0.001% to 0.01% moisture content. Think about your throughput needs and whether rapid measurement times are essential. Check the maximum sample weight capacity matches your typical sample sizes. Also consider ease of use, data management features, and compliance requirements for your industry. The M Series with its fast heating and uniform temperature distribution is ideal for applications requiring both speed and precision.
Regular maintenance ensures optimal performance and longevity of your moisture analyser. Keep the heating chamber and sample pan clean, removing any residue after each use. Regularly calibrate the instrument using certified reference materials or standard weights to maintain accuracy. Inspect the halogen lamp periodically and replace it according to manufacturer recommendations. Clean the protective glass or filter to ensure efficient heat transfer. Store the instrument in a stable environment away from vibrations, direct sunlight, and temperature fluctuations. Following these practices will maintain measurement precision and extend equipment life.
Yes, modern moisture analysers are versatile instruments capable of handling a wide range of sample types. They can analyse powders, granules, pastes, slurries, liquids, and solid materials. The key is selecting appropriate heating profiles and parameters for each sample type. Temperature-sensitive materials require lower heating temperatures or gradual heating ramps to prevent sample degradation or burning. Dense samples may need longer heating times for moisture to fully evaporate. Most moisture analysers offer programmable methods that can be saved and recalled for different sample types, ensuring consistent testing procedures across your quality control processes.
Moisture analysers provide comprehensive measurement data beyond just the final moisture percentage. They typically display moisture content, dry content, and the actual weight loss during drying. Many models show real-time drying curves, allowing you to monitor the evaporation process. Results can include measurement duration, heating temperature, and final sample weight. Advanced units offer data storage capabilities, allowing you to save results for quality control records and regulatory compliance. Some instruments feature connectivity options for exporting data to computers or laboratory information management systems (LIMS), facilitating seamless documentation and analysis of moisture trends over time.
Measurement time varies depending on the sample type, moisture content, and desired accuracy. With advanced halogen technology like the M Series with SRA filter, many analyses complete in 3-15 minutes. Samples with high moisture content or those requiring lower temperatures may take longer. Conversely, low-moisture samples or those that can withstand higher temperatures often finish in just a few minutes. The rapid heating and uniform temperature distribution of modern moisture analysers significantly reduce measurement times compared to traditional oven methods, which can take several hours, improving laboratory productivity and enabling faster quality control decisions.
Modern moisture analysers are designed for ease of use, making them accessible even to operators with minimal training. Most feature intuitive touchscreen interfaces or simple button controls with clear menu navigation. Pre-programmed methods can be stored and recalled with a single touch, ensuring consistency between operators and reducing setup time. The automated measurement process eliminates subjective interpretation – simply place the sample, start the analysis, and the instrument does the rest. Built-in guidance and help functions assist with troubleshooting. While initial training on proper sampling techniques and method development is important, day-to-day operation is straightforward and efficient.
