Ensure Accuracy and Reliability with Performance Verification

To ensure that the measurement cell of your density meter or refractometer is clean and free from sample residuals from previous measurements, a basic check with deionized water is sufficient during routine operation. But what if your quality management system demands higher standards for traceability and regulatory compliance?

Our preventive maintenance and calibration services encompass comprehensive performance verification and certification, utilizing certified reference standards to ensure complete traceability. The same standards can be used for your own, more frequent performance verification.

FAQs

What is covered with preventive maintenance of a density meter and/or refractometer?

The following tasks are executed during preventive maintenance:

Thorough investigation of instrument status "as found", including performance verification with air and/or deionized water
Visual checks and cleaning of housing, surfaces, terminal, and covers, as well as accessories (pumps, valves) and peripheral devices
Replacement of worn parts such as cell- and syringe adapters, O-rings, and protective sleeve/lid, if required
Operational testing of instrument boards and terminal, temperature monitoring, thermo module, and fan check
For density measuring cells only: additional leakage test, oscillator check, and cell view adjustment
Performance verification "as left"
Detailed maintenance report and recommendations for routine operation and instrument care

Can METTLER TOLEDO also service an autosampler used with a density meter and/or refractometer?

Yes, we offer preventive maintenance for our sample changers and InMotion™ autosamplers. The service includes thorough visual inspection and cleaning, functional and operational testing, and adjustments, if required.

How can I detect if my density meter or refractometer needs maintenance or repair?

Signs that indicate your density meter or refractometer requires maintenance or repair include:

Inconsistent or inaccurate readings
Slow response times/temperature adjustments of the measuring cell
Physical damage
Unusual noises

Regular performance verification and calibration can help to identify possible issues early. If you notice any of these signs, it’s advisable to consult a professional service.
