What to do if OHAUS Measuring Instruments shows “Close Cover”?
If the OHAUS Measuring Instrument displays “Close Cover”, it means the cover needs to be closed before starting the test. Please close the cover to proceed.
What to do if OHAUS Measuring Instruments shows “Tare”?
If the OHAUS Measuring Instrument shows “Tare”, it indicates that the pan weight needs to be set to zero. Press the Tare button to zero the pan weight.
Why is the weight value blinking on my OHAUS Measuring Instruments?
If the OHAUS Measuring Instrument displays a blinking weight value, it means the sample weight is less than 0.5g. Increase the sample size to resolve this issue.
What does Err 8.3 mean on OHAUS Measuring Instruments?
If the OHAUS Measuring Instrument shows Err 8.3, it means the weight on the pan support exceeds capacity. Remove weight from the pan support.
What does Err 8.1 mean on OHAUS Measuring Instruments?
If the OHAUS Measuring Instrument shows Err 8.1, it indicates that the pan support has a load during power on. Remove any weight from the pan support.
What does Err 8.5 mean on OHAUS Measuring Instruments?
If the OHAUS Measuring Instrument displays Err 8.5, it means the analyzer temperature is above 50°C. Cool down the analyzer.
What does Err 8.6 mean on OHAUS Measuring Instruments?
If the OHAUS Measuring Instrument shows Err 8.6, it means the analyzer temperature is higher than the target setting. Cool down the analyzer.
How to improve accuracy of OHAUS Measuring Instruments?
If you are experiencing poor accuracy with your OHAUS Measuring Instrument, perform a calibration. Also, move the analyzer to a more stable location.
What does Err 8.4 mean on OHAUS Measuring Instruments?
If the OHAUS Measuring Instrument shows Err 8.4, it indicates that the pan support was removed during weighing. Re-install the pan support.
What does Err 8.2 mean on OHAUS Measuring Instruments?
If the OHAUS Measuring Instrument shows Err 8.2, it means the pan support was removed prior to power on. Install the pan support.

The OHAUS MB23 / MB25 Moisture Analyzer is a precision instrument designed for the accurate determination of moisture content in various samples. Its primary function is to measure the weight loss of a sample as it is heated, thereby calculating the moisture percentage. This process is crucial in many industries for quality control, research, and development.
The moisture analyzer operates on the thermogravimetric principle, where a sample is weighed, then heated by a halogen or infrared heating element (depending on the model) to evaporate its moisture. The instrument continuously monitors the sample's weight during the drying process. Once the weight stabilizes, indicating that all moisture has been removed, the analyzer calculates the moisture content based on the initial and final weights. The MB23 and MB25 models offer different levels of readability and capacity, catering to a range of application needs.
The analyzer features a clear display that shows various parameters during operation, including temperature, time, current weight, and calculated moisture or solids percentage. It provides stable indicators to ensure reliable readings. The intuitive control panel with dedicated buttons for functions like "On/Off," "Start/Stop," "Tare," "Temp," "Time," "Set ▲/▼," "Print/Cal," and "%g" allows for easy navigation and operation.
The device supports multiple operating modes:
The MB23 / MB25 is designed for user-friendliness and flexibility in various laboratory and industrial settings.
The MB23 / MB25 Moisture Analyzer is designed for robust performance, with minimal maintenance requirements.
The OHAUS MB23 / MB25 Moisture Analyzer is a reliable and versatile tool, offering precise moisture determination capabilities with user-friendly operation and clear maintenance guidelines, ensuring consistent and accurate results for a wide range of applications.
