ph-203 Digital PH/ORP Controller

The ozonier did stop at 350.I saw the ozoniser off when the ORP reach 350.
But the ORP reading still going up and stablise at 380.

Regards

Now is 2100.ORP reading still 370.
Maybe will drop to below 350 after midnite.
Then ozoniser will run again
So far only run 1/2 hours since noon.

380mV is still within the limits of the safety zone.

Woa, power leh.. after cut-off at 350. it still can move to 370-380mV.
very good leh...I think must try using the Hailea Ozone liao.

err....I think this is bec the probe is not fully 'seasoned' yet, as mentioned by the other Bro who has done the few test.

I suggest anyone using a new probe should only start ozonizer after 1-2 week, when the probe reading is stablised. Otherwise, u will risk overdose due to the 'Not ready' reading given out by the new probe.

Hee hee bro u refering to me ? I agree w yr statement , that one shld not start the Ozone until the probe has been in used for at least 1 -2 weeks , for my case , recommended 4 days to 1 week.

Guyzs, too boh liao , did another test this afternoon using TransInstrument Redox soln 475mV @ 25 oC . Reading from China probe is 440mV . imho , quite good alreadi.
Was talking to the mkting Asst of Trans Instrument and she told me that probes deviation usually -/+ 30 to 40 mV , so I think China probe is quite good , except u guyzs very Kan -Cheong one leh , want instant result

No need for my name , cos we r here to share , not interested in recognition nor credit...
