Why is calibration important for my instruments?

Calibration is essential to determining the reliability and quality of your pH measurements. It ensures that your pH instruments work within their specified ranges and provide accurate readings. Regular calibration helps to minimize errors and gain confidence in your measurements.

How often should I have my instruments calibrated?

The calibration frequency depends on various factors, including the type of instrument, its intended use, and the number of samples. Generally, most instruments should be calibrated at least once a year and more often if used frequently or subject to harsh environmental conditions.

What calibration standards do you use?

At METTLER TOLEDO, we adhere to national and international calibration standards, including ISO 9001 and NIST traceability. This ensures our calibration procedures meet rigorous quality standards and provide accurate and reliable results.

Can you calibrate my instruments on-site, or do I need to send them to your facility?

Depending on your business needs, we offer both on-site and off-site calibration services. Our expert technicians can perform calibration services at your facility, minimizing downtime and ensuring the accuracy of your instruments.

How long does the calibration service process take?

The time required for calibration depends on the instrument being calibrated, the complexity of the procedure, and other factors. Our technicians will provide you with an estimated timeline for calibration, and we strive to complete all calibration services as quickly as possible while maintaining the highest accuracy and quality.
