Professional Moisture Analysers for Advanced Moisture Analysis
Measuring moisture content has never been easier than with the Ohaus MB120 and MB90 Moisture Analysers.  Geared to increase precision and efficiency in the lab, these Moisture Analysers feature a precisely controlled halogen heating system which helps to yield fast and repeatable results with readability up to 0.01%. The robust housing and die-cast structure is designed for easy, tool-free cleaning and durability.  An intuitive touchscreen icon-driven menu guides users through every step of the operation process.

Standard Features Include:

  • Define your Drying Parameters and Store Up to 100 Methods for Easy Recall
    MB120’s Temperature Guide helps to analyse a sample and determine the optimal drying temperature. You can store up to 100 methods and 1000 total results, for statistical analysis
    of measurements. Three levels of user management are available to meet individual user requirements and ensure data safety.
  • Increase Efficiency in your Lab with Fast Heating Halogen Technology
    A precisely controlled halogen heating system distributes heat uniformly over the sample, ensuring fast and repeatable results. Four selectable drying profiles for easy one-step drying and
    seven shut-off criteria to automatically end the test (once moisture loss is no longer detected) are available in the MB120.
  • Effortless Cleaning with the Tool-Free Cleaning Structure
    Designed with convenient maintenance in mind, no tools are required for cleaning these moisture analysers. Simply remove the glass and tray to clean the sample chamber.
    The robust housing and die-cast base guarantee durability.
  • Operate Intuitively Using Icon-Based Navigation on the Colour Touchscreen Display
    You can access all of the MB120 and MB90’s features and parameters on the easy-to-read colour touchscreen display. The intuitive icon-based navigation guides users through every step of the operation process.

    Customise heating of specific samples with temperature control for one-step drying—set temperature and time and begin!
    Fast: Quickest possible time to temperature
    Standard: Minimal overshoot while achieving temperatures quickly
    Ramp: Controlled ramping to temperatures (MB120 only)
    Step: Set three temperatures at three time intervals
    (MB120 only)
  • Shut-Off Criteria for Automatic Test Completion
    Customise your own test endpoint criteria to automatically
    end the test once moisture loss is no longer detected.
    Choose from up to 7 criteria on MB120 —Manual, Timed,
    Auto, Auto-free percent weight loss per second, Auto-free
    mg loss per second, A30, A60 and A90 or up to 3 criteria on
    MB90 — Manual, Timed, Auto
