To guarantee maximum traceability, a global test certificate exists for all redox buffers. Contact your METTLER TOLEDO representative to acquire the test certificate.
Compliance with GHS
Remaining compliant with regulations is important. All of our SDS (Safety Data Sheet) and labels contain information according to GHS (Global Harmonized System) in local languages.Download your SDS here
Discard Expired Buffer
The expiry date indicates until which date the certificate guarantees the value and the associated measurement uncertainty. After this date the uncertainty cannot be guaranteed.
Use a fresh aliquot of buffer for each calibration to ensure no contamination enters the bottle. Do not calibrate directly in the solution bottle.
Use enough buffer for accurate calibrations. The sensor should be submerged in the solution in order to achieve the most accurate results.

What is an ORP buffer used for?
ORP buffer solutions are used for verification of all common redox sensors. They are not used for calibration purposes. Similar to other solutions, an ORP buffer is temperature dependent. It is therefore important to know the measurement temperature of the ORP buffer. A table on every bottle label indicates redox values at different temperatures.
Where can I obtain a certificate for my ORP Buffer?
All METTLER TOLEDO ORP buffer solutions are available in handy bottles with no-fuss labels. If larger quantities are required, then our 6-packs are the right choice. To guarantee maximum traceability, a global test certificate exists for all redox buffers. Furthermore, compliance with regulations is key for us. All SDS (Safety Data Sheet) and labels contain information according to GHS (Globally Harmonized System) in local languages.
If you need a document to verify the certificated production of these ORP buffers, please contact your dealer or local METTLER TOLEDO representative, whom you will find in the contact section at www.mt.com.
