there is a discount when you buy 2 redox and ph probes

Hello

No, unfortunately we don't have that, but shipping is free

what about the guarantee1

The guarantee is 1 year

our last probe could not be calibrated within a season? You can't buy a new one every year!

We know that 82% of our probes are more than 3 years old. A probe is a battery and therefore has a lifetime. It's technology

and it doesn't just depend on the probe

Sure, but how should we behave . just send it back or what?

Yes, let you know if there is any problem. If the problem is clear, we will send you a probe. In some cases you may be asked to send it back to us for analysis

Okay, we've already considered whether regulating the pool by hand is cheaper!

how can you check the function of the probe yourself?

According to our information, the regulation saves PH liquid. Controller manufacturers promise time and money savings

for redox: https://ph-redox-pool.com/de/content/17-ist-meine-redox-sonde-außer-betrieb

What do controller manufacturers mean when they promise time and money savings and what can you use to measure mV?

You can usually read this value on the controller

Money because you dose the necessary ph liquid precisely and time because it is automatic
