Frequently Asked Questions

Never store long term in distilled or deionized water. Use an electrode storage.

Calibrate daily for professional use or before every critical measurement session. Sensors drift, calibration anchors your data.

Probes will eventually deteriorate. Proper storage and cleaning will extend their lives. Expect 12-24 months with proper maintenance. Sluggish readings or difficulty during calibration may signal that it's time to consider a replacement.

Absolutely. Relative Humidity (RH) is temperature-dependent. For the most accurate data, always allow the instrument to reach thermal equilibrium with the environment.
