To correctly calibrate a swimming pool probe, you need: a swimming pool probe, and ... a swimming pool buffer solution which will allow this probe to be calibrated!

Buffer solution for swimming pools: why?

In the world of swimming pools, when we talk about " buffer solution for swimming pool Is that we have a very specific objective in mind: to calibrate our pool probe.
Indeed, when you want to measure the salt level, the bromine level, the chlorine level or even the pH of the water with electronic testers (pH meter, pH regulator, chlorine regulator, etc.) equipped with an electrode probe, for the measurements to be fair and precise, it is imperative calibrate the probe when commissioning the device, and the return to service of the swimming pool in the spring.

And to calibrate the probe effectively, it must be dive into a reference solution, also called standard solution, or buffer solution; this maneuver will allow the probe to fix the reference value on which it will always have to be based to evaluate the levels of a particular product in the water.
