OHAUS MB120-EU moisture analyzer
The OHAUS MB120-EU moisture analyzer is specially designed to determine the moisture content of samples quickly and reliably. The device impresses with its high repeatability and wide range of customization options, making it the ideal tool for demanding applications such as laboratory analysis, food control or quality control in industrial processes. Compared to many other moisture analyzers, the MB120-EU model ensures significantly more efficient sample analysis thanks to its modern halogen beam technology and intuitive ease of use.
Precision and flexibility for demanding measurements
The halogen lamps provide uniform heat distribution and therefore accelerate the drying of your samples. As a result, extremely precise moisture values can be determined within a short period of time and reproducible results can be produced multiple times. Thanks to the large 4.3-inch touch display and the user-friendly menu structure, both routine tasks and complex analyses can be carried out effortlessly. Another plus point is the robust metal housing, which, in combination with ABS top flaps, ensures durability and enables use in demanding laboratory or production environments.
The drying methods can be set using different profiles. Standard, ramp, step and fast are available, making sample analysis individually customizable. Alternatively, various switch-off criteria (e.g. time-controlled or manual) support consistent measurement accuracy. The storage of up to 100 methods also speeds up recurring measurement sequences and increases productivity.
Main technical features at a glance
- Maximum weighing capacity: 120 g
- Readability: 1 mg or 0.01 % for moisture measurements
- Weighing pan size: 90 mm
- Heater: Halogen heater for quick and even drying
- Temperature range: 40 °C to 230 °C
- Communication: USB device, USB host (2x), RS232
- Large touch display: 4.3 inch color WQVGA touch screen
In addition to these main features, the device has many other functions, including an integrated test library for up to 100 data sets and a protective cover that protects the device from splashes or dust. The measured values can be saved directly to a USB stick or retrieved via the RS232 interface. The operating range extends from -10 °C to 40 °C, with a maximum relative humidity of 85 %, non-condensing. This makes the humidity determination system suitable for different environmental conditions.
The integrated menus for GLP/GMP-compliant data output support compliance with common quality standards and documentation requirements. This function is a great advantage, especially in laboratories that strive for certifications such as DIN ISO or have to prove their compliance. The device itself works reliably in a temperature range of 10 °C to 40 °C, which corresponds to a typical laboratory environment.
Typical application examples in laboratory and industry
The MB120-EU model can be used across all industries, particularly in laboratories, production facilities and quality control areas. Specific applications include:
- Food production: determining the moisture content of flour, cocoa, tea or cereal products
- Pharmaceutical industry: testing powder preparations and checking the residual moisture content in tablets.
- Chemical production: checking reaction residues in resins, plastics or emulsions.
- Cosmetics sector: measurement of moisture content in creams, lotions or masks to ensure consistency and shelf life
The device is also suitable for other areas such as research facilities and material and raw material analyses. Thanks to the flexible method management, users always achieve reproducible results for every product type.
Frequently asked questions (FAQ)
How often should the device be calibrated?
Regular calibration, ideally at least once a year, is recommended to ensure long-term accuracy. Depending on the frequency and intensity of use, shorter calibration intervals may be advisable.
Do I need to use a special sample container?
The device is usually supplied with suitable sample pans. However, thanks to the generous weighing pan size of 90 mm, other suitable vessels can also be used as long as they meet the specifications of the device.
What needs to be considered during the heating process
A gentle drying approach (e.g. ramp) should be selected first, especially for very sensitive samples or heat-sensitive substances, in order to avoid measurement inaccuracies. The halogen lamps ensure rapid heat transfer, so it is advisable to set the starting temperature range carefully.
What sample quantities are optimal
Sample weights between 0.5 g and 120 g are usually used. In general, a sufficient sample quantity of around two to ten grams offers a good balance between reproducibility and fast drying time.
How to clean the device
After each use, it is advisable to clean the sample chamber and the protective cover to avoid cross-contamination. The device should be protected from aggressive chemicals and only cleaned with suitable, mild cleaning agents.
Summary
The modular structure, sophisticated menu design and fast halogen drying make this moisture analyzer a reliable and versatile partner in the laboratory and in industrial production. Thanks to the user-friendly touch display and the flexible drying methods, both routine samples and demanding measurement series can be evaluated conveniently and precisely. The model offers a robust design, comprehensive temperature and method management as well as good interface solutions for seamless data evaluation. If you are looking for a high-performance and user-friendly moisture analysis solution, the MB120-EU is the ideal choice.
