What is the best way to determine if a recurrent OPI leak during standard operation is due to a faulty/ fouled OPI probe head or a fouled/damaged electrode or poor flow rate optimization?
If you replace the OPI probe head or OPP, what is the protocol for this? Is a new electrode also installed? Is flowrate optimisation required again?
The OPI probe head seems like it has an accumulation of precipitate externally which can be removed with water, how is this best avoided?
Has anyone else had recurrent OPI leaks and how have you dealt with them?
Thanks for your help!
