Moisture Analysers – Precise moisture analysis for laboratories, industry and research
A moisture analyser, also known as a drying balance or moisture balance, is a specialised piece of laboratory equipment used for the rapid and precise determination of the moisture content of a wide variety of substances. The measurement is carried out according to the thermogravimetric principle: the sample is weighed on an integrated balance whilst a heating element – usually halogen, a quartz glass heater, an infrared heater or a metal heating element – specifically heats and dries the sample. During the drying process, the balance continuously measures the sample’s weight; the loss in weight corresponds to the water that has evaporated and is displayed as the moisture content.
Moisture analysers have become an indispensable part of modern laboratories. They are used in the food industry, the chemical industry, the pharmaceutical industry, sewage treatment plants, the wood-based materials and construction materials industries, as well as in quality control for pastes, powders, coatings and granulates. Reliable measurement results for laboratory moisture content and dry matter are crucial, particularly in the development, production and monitoring of materials.
Design, technology and key features of modern moisture analysers
Components and measuring principle
A typical laboratory moisture analyser consists of:
- Weighing range: Depending on the model, usually between 35 and 400 g.
- Readability: High-precision models offer an accuracy of up to 0.001 g and a moisture resolution of 0.01%.
- Heating element: Halogen, infrared, quartz glass or metal heating elements ensure uniform and rapid heating.
- Drying programmes: Various heating profiles (standard, rapid, gentle or step drying) and individually adjustable drying temperatures (usually 35–250 °C; up to 360 °C for specialised models).
- Sample dishes: For weighing and the even distribution of the sample.
- Shut-off criteria: Automatic (when mass is stable), time-controlled or manual.
- Data interfaces: USB, RS232, Ethernet or Wi-Fi for data transfer and GLP-compliant logging to a PC or printer.
Typical applications of moisture analysers
Moisture analysers are used in many areas:
- Monitoring the moisture content in foodstuffs, animal feed, cereals and flour
- Determining the water content in pastes, creams, spreads and powders
- Quality control in the plastics, chemical and building materials industries
- Monitoring of sewage sludge and biomass in sewage treatment works
- Moisture analysis in wood-based materials, pellets and wood chips
- Research and development of new materials and formulations
Benefits at a glance
Moisture analysers impress with their precise and rapid determination of moisture content in a wide variety of substances. Thanks to their versatile heating profiles, they are ideally suited to pastes, powders, granules, wood-based materials, coatings and many other materials. They offer high accuracy and reproducibility of measurement results, so you can rely on trustworthy outcomes. Operation is particularly user-friendly – even inexperienced users can quickly find their way around thanks to the touchscreen or intuitive menu navigation. The robust design allows for easy cleaning and maintenance. You also benefit from flexible data management and secure logging of measurement results, ensuring maximum transparency both in the laboratory and in production.
