Inline pH electrode system - For continual online pH measurement. 

 

Quick release inline pH electrode holder - PES-1-QR

Inline pH electrode holder with quick release

The PES-1-QR is out inline pH electrode holder for use in 3/4" pipework. 

The unit allows a pH electrode to be held in pipework to give a continuous online pH measurement when accompanied with an appropriate pH instrument. 

The PES-1-QR allows the quick release of the pH electrode for maintenance or buffering / calibration.

The inline pH electrode system forms part of the pipework as a permanent installation and the pH electrode can be easily removed in minutes without the need for special tools.

Inline pH electrode system for larger diameter pipes - PES-2-QR

For larger diameter pipework we offer the PES-2-QR which works with our PS183-20B from the industrial pH probe range.

The PES-2-QR is designed to become part of the pipework and the specially manufactured quick release fitting is designed to allow the pH probe to be removed easily form inline pH electrode system in minutes - without the need for special tools. 

The PES-2-QR inline pH electrode system is normally solvent welded into 2" diameter pipework.

Retractable pH electrode system - Lock-n-Load

The lock-n-load inline pH electrode system differs from our standard range by offering a unique internally sealed retractable mechanism. 

With normal inline pH electrode systems the process needs to be stopped and the measured fluid needs to be isolated and drained before the pH electrode can be removed. 

With the Lock 'N' Load system - the process doesn't need to be stopped the pH probe in the Lock 'N' Load is simply retracted, locked into place, and the probe can be removed while the system is completely sealed. 

There are no need for valves, retaining cables, or special tools - the lock 'n' load means that probes can be removed from pipework in a matter of minutes.

Inline pH electrode systems

When measuring the pH of a process that is contained within a pipe it can be tempting to thead the pipe and install a pH probe with the corresponding thread.

This can sometimes cause difficulty when it comes to removing the probe either for maintenance, replacement or for a standard calibration.

For an easy way to remove the pH sensor we recommend using one of our inline pH electrode systems - we have the PES-1-QR assembly for 3/4" pipework and the PES-2-QR inline pH electrode system for larger diameter pipes. These two systems and solvent welded into the pipework (or they can be supplied with threaded connections on request) to form an integral part of the pipework. Then when it's time to remove the pH electrode and the pipework has been drained and isolated - the pH electrode is removed from the inline electrode system using the quick release fitting. This takes a matter of minutes for easy maintenance.

Alternatively - we have the Lock 'N' Load retractable inline pH electrode system. This system is sealed from inside the end cap - so the retracting section of the Lock 'N" Load won't fly off under pressure and it also creates a seal with the pipework. When it's locked into place the pH electrode can be removed without having to isolate and drain the pipework. There are no retro valves or retaining cables - just a simple lift, twist and lock to remove the electrode and carry out any maintenance.
