Probes FAQ

What is a multiparameter probe?

A multiparameter probe measures several properties of a solution at once—like pH, oxidation reduction potential (ORP), electrical conductivity (EC), and/or temperature. By combining multiple sensors in a single device, it delivers fast, accurate readings without the need for multiple instruments, making lab and field testing simpler and more efficient.

What measurements can a multiparameter probe take?

Multiparameter probes can measure pH, oxidation reduction potential (ORP), electrical conductivity (EC), temperature, and/or sometimes other parameters depending on the model. This lets you get multiple readings with a single device.

Are the probes compatible with smartphones or tablets?

Yes! All of our multiparameter probes feature wireless Bluetooth connectivity and integrate with our smartphone app for easy measurement, logging, and analysis. To download the app, search Sentron in your app store.
