Hello, I have a problem measuring PH.

Hello, what's going on?

the Ph measurement has gone from 7.2 to 3.8 and has remained at 3.8 for several days

Take this test: https://ph-redox-pool.com/gb/content/16-ma-sonde-ph-est-elle-hors-service-

with a biouv combipool

Try this test because a value of 3.8 is not normal

ok thank you i will do the test

You are welcome, do not hesitate to contact us! Have a good day

Hello again

Hello again

problem there is no more flow I cannot read the PH

Do you have a cap to replace the probe? Or an old probe?

no Unfortunately

what is the lifespan of a sensor?

It is variable, from 2 years to 15 years

Usually 3 years

She's 4 years

I think it no longer works for 2 reasons. the value at 3.8 is too low and in addition the value no longer moves

yes you are right I will order one how long is the delay?

4 working days

OK, thanks
