FAQ – Meytec 475 mV ORP Buffer Solution

What is Meytec 475 mV ORP Buffer Solution?

It is a ready-to-use 475 mV reference solution, designed for the precise calibration of Oxidation-Reduction Potential (ORP) probes used in swimming pools and spas.

Why calibrate an ORP probe at 475 mV?

The 475 mV value is a stable and central reference point for most pool/spa applications. It allows the sensor to be adjusted to obtain reliable and comparable measurements over time.

Which devices and probes is the solution compatible with?

It is compatible with all common ORP probes and measuring devices, regardless of brand and model, as long as fixed-point calibration is supported.

How do I use the buffer solution to calibrate my ORP probe?
  1. Rinse the probe with distilled water and blot it gently.
  2. Pour some 475 mV ORP buffer solution into a clean container.
  3. Immerse the electrode and wait for the reading to stabilize.
  4. Adjust the device to 475 mV according to the manufacturer's instructions.
  5. Rinse the probe with distilled water after calibration.
How often should I calibrate my ORP probe?

Calibrate at least once a month or according to the manufacturer's recommendations, and after any major intervention (probe replacement, winterization, chemical shock).

Is the solution ready-to-use or does it require preparation?

It is ready-to-use. Do not add anything or dilute it. Use small quantities in a clean container to avoid contaminating the bottle.

Can I reuse the solution once poured into a container?

No. Discard any portion taken after use. To maintain accuracy, never return used solution to the original bottle.

How should I store the 475 mV ORP buffer solution correctly?

Keep the bottle tightly closed, away from light and heat, in a clean place. Avoid temperature variations and contamination of the neck.

What is the shelf life or expiration date of the buffer solution?

Refer to the date indicated by the manufacturer. Generally, a properly stored solution remains reliable until its best-before date, but replace it if its appearance changes or after prolonged opening.

Does temperature influence the ORP value of the 475 mV solution?

Yes, ORP is slightly temperature-dependent. Ideally, calibrate at a stable ambient temperature and allow the probe to stabilize before adjusting the device to 475 mV.

Can I use the 475 mV solution to check a measurement on-site, without recalibrating?

Yes, you can use it as a control solution. If the deviation is significant, perform a full calibration according to your device's instructions.

What safety precautions should I observe when using the buffer solution?
  • Use clean containers to avoid contamination.
  • Avoid contact with eyes and mouth; do not ingest.
  • Close the bottle carefully after use.
  • Keep out of reach of children and animals.
