Inline pH electrode holder with quick release - PES-1-QR

Inline pH electrode holder with quick release PES-1-QR

The PES1-QR is an inline pH electrode holder designed to hold any of our range of pH electrodes fitted with the Ryton flared cap.

Inline pH electrode Holder PES-1-QR

The PES-1-QR inline pH electrode holder is designed as a flow line system in 3/4" Tee piece. The standard PES-1-QR is manufactured in PVC and supplied with our 9069-10B glass bodied pH electrode. The unit becomes a permanent piece of the pipework ensuring that the pH can be measured constantly.

Inline pH electrode holder PES-1-QR Features & Benefits.

The PES-1-QR inline pH electrode holder features our specially manufactured quick release fitting. This means that any of our flanged pH electrodes can be held in place using the quick release fitting. The quick release fitting incorporates an electrode guard to protect against solids or abrasives from damaging the glass bulb of the pH electrode as well as allowing an easy removal of the pH probe for buffering and calibration procedures.

The 3/4" Tee piece is designed to be held in with a solvent weld but other fitting types are available. Where ever possible we recommend that electrodes are installed in a sample line piped to drain or a low pressure point in the system. If the solution to be measured has a high temperature the installation of a sample cooler will lengthen the electrode life. 

Inline pH Electrode Holder PES-1-QR in Summary.

The PES-1-QR is manufactured in PVC as standard, for 3/4" solvent weld installation or 1/2" BSP and supplied complete with the 9069-10B glass bodied pH probe.

Our standard models include:-

In addition to our models within a 3/4" tee piece we also offer models within a 3/4" cross piece. This includes platinum resistive temperature device or thermocouple which can be used for either temperature measurement or for temperature compensation. These models are designated as PES-1-QR-TC1 for PVC, PES-1-K for Kynar (PVDF) and PES-3-QR-TC1 for 316 stainless steel.

PES-1-QR Inline Electrode Holder

Accessories for the PES-1-QR Inline pH electrode holder and items also purchased by AWE Direct customers that purchased this item:-

 

Glass Bodied pH Electrode 9069-10B

The 9069-10B is our standard glass bodied pH electrode. The electrode is designed to work with our PES-1-QR inline pH electrode holder as well as a stand alone pH electrode for light industrial or laboratory usage.

pH Electrode 9069-10B

The 9069-10B is rated to 60ºC and offers a very quick response time, has a non-fouling annular reference junction, and is supplied complete with 3 metres of connecting cable & BNC plug. 

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.
