Retractable Inline pH electrode system for pressurised pipes - Lock 'N' Load

Retractable inline pH electrode system Lock-N-Load

The Lock-N-Load is a retractable inline pH electrode system for use in pressurised pipes. 

Retractable Inline pH electrode system Lock-N-Load

The Lock-N-Load inline pH electrode system is designed to hold a pH electrode in a pressurised pipe for constant online pH measurement. The unique design of the retractable Lock-N-Load system allows the pH electrode to be removed from the pipework without the need to stop the flow in the pipe. The Lock-N-Load literally locks into place sealing the pipe and allowing easy removal of the pH probe for buffering or calibration. When calibrated the probe is simply inserted back into the Lock-N-Load and lowered into the pipework, then locked into place for continuous online pH monitoring.

Retractable Inline pH electrode system Lock-N-Load

The retractable inline pH electrode system becomes is designed to become part of the pipework as a permanent installation. It has an insertion length of 63mm and the 9392 pH electrode which is available with either glass body or Stainles Steel sheeth - is lowered into place to give continuous pH monitoring. When the time comes to replace the pH electrode a simple twist of the lock-n-load will release the locking mechanism. The pH electrode is then lifted out of the pipework and the lock-n-load is locked back into place. The electrode can no be safely removed for calibration or replacement. The solution in the pipework doesn't need to be stopped or drained and the electrode can be removed "on the fly" without the need to interupt the process. 

The Lock-N-Load is designed to be as safe as possible - the end cap seals from the inside out - so there is no need to rely on valves or retaining cables like older solutions popular in mid 1980's.

The retractable pH electrode system the Lock-N-Load is available in PVC, Kynar (PVDF) or 316 Stainless Steel which allows the Lock-N-Load assembly to be used in a wide range of applications in Water, Effluent Treatment and Process Control.

Replacement pH electrode 9392-10B

The 9392-10B is a long bodied pH electrode designed for use specifically with the retractable pH electrode holder the Lock 'N' Load.

replacement pH electrode 9392-10B

The 9392-10B pH electrode for the lock 'N' load combines a number of technologies to give a double junction pH probe resistant to electrode poisoning, rated to 100ºC and offers a very quick response time. The reference junction is a non-fouling annular type and the probe comes as standard with 3 metres of connecting cable and BNC plug.

In addition to the standad glass body the 9392-10B is available with a stainless steel sheath for use with the stainless steel Lock 'N' Load retractable pH electrode holder - use part number 9392-SS-10B.

 

P7685:- 96 x 96mm pH Controller for proportional dosing and expandable 4-20mA output

AWE Direct offer the AWE Instruments P7685 pH controller for proportional dosing which offers two proportional control relays and an expandable 4-20mA output . 

P7685 pH controller for proportional dosing

The P7685 pH controller for proportional dosing combines an isolated current output (0 - 20mA or 4 - 20mA) which can be expanded or inverted to cover the 0 - 14.00 pH range. In addition the 2 control relays can be used on either Pulse Frequency Modulation (PFM) to control the frequency or number of strokes per minute that a compatible proportional control dosing pump makes, or the 2 control relays can be used as Pulse Width Modulation or PWM control relays to control proportional solenoid valves. The P7685 pH controller is also fitted with delay timers, an alarm relay with delay timer and bright LCD display all in a compact 96 x 96 mm case.
