Moisture Analyzer Calibration and Routine Testing

Keep Your Moisture Analysis Accurate

Home Laboratory Weighing Moisture Analyzer Calibration and Routine Testing

The accuracy of moisture analyzer results can become less reliable over time because of normal wear and tear. External influences such as the ambient temperature or drafts can also cause errors in results.

To ensure reliable moisture content determination and correct instrument function, regular calibration and testing of your moisture analyzer's heating and weighing unit is essential.

Why Do I Need a Balance or Scale Calibration With a Certificate?

Accuracy Calibration and Moisture Analyzer Certificates: Assess Your Weighing and Heating Units

The Accuracy Calibration Certificate (ACC) assesses the performance of the weighing unit over the entire weighing range to establish measurement uncertainty.

By combining this assessment with the Moisture Analyzer Certificate, you have the heating unit assessed with the SmartCal™ test substance and temperature kit at the same service visit. This gives you peace of mind that the weighing and heating units are working correctly and supplies you with the proper documentation to prove it. 

Routine Testing to Monitor Performance

While moisture analyzer calibrations are performed by a service technician, regular testing of a moisture analyzer against set tolerance limits is typically performed by a user. This routine testing gives you confidence that your measurements are correct on an ongoing basis.

Our Good Moisture Analysis Practice (GMAP) provides you with a risk-based routine testing plan that helps you ensure consistent product quality. The comprehensive plan includes recommendations for test frequency, test methods/SOPs, test weights and test tolerances.

Recommended routine tests are:

  • SmartCal™
  • Temperature
  • Weight

Fast Performance Checks with SmartCal

SmartCal™ provides a rapid method for verification of overall moisture analyzer performance in just 10 minutes. This unique test substance with a specific moisture content tests both the heating and weighing elements simultaneously.

Regular testing between calibration intervals with SmartCal is a fast, easy and cost-effective way to ensure reliable measurement results and meet the demands of industry quality regulations on an ongoing basis.

How can I get in contact with a Service Technician?

You have two ways to contact us. If you want to have your device repaired onsite or in one of our service repair centers, you can either fill out a "Request Service" form or contact us directly by phone. Both options are available at our Customer Support link.

How often should I perform routine tests?

Routine testing, which includes testing overall instrument performance using SmartCal™, tests both weighing and heating units, shortens periods of uncertainty between service visits and helps to ensure quality results. While routine testing should be performed at regular intervals, frequency depends on a risk evaluation for each application and process. Good Moisture Analysis Practice can help with this risk-assessment and provide a recommendation for routine testing frequency. 

Can all moisture analyzers from METTLER TOLEDO be assessed using SmartCal™?

Yes, the SmartCal test substance can be used for testing the overall instrument performance of any METTLER TOLEDO moisture analyzer. Independent of instrument type, you get results within 10 minutes.
