pH Control System

A complete pH setpoint control package on a PVC backboard, built around the PH-XP2 digital controller with on-board data logging. The pH probe, probe holder, manifold with dosing point and return to tower, self-priming SEKO peristaltic pump rated 1.3 L/h at 3 bar and a flow switch are all included, so the system only doses when there is flow and the reading is off setpoint. Available open or in a hinged lockable cabinet.

pH Control System

Product Information

Key Features

  • Complete pH setpoint control package — PH-XP2 digital controller, pH probe and holder, manifold with dosing point and return to tower, peristaltic dosing pump and flow switch, all mounted on a PVC backboard
  • Measures pH continuously and drives the dosing pump to hold your setpoint, with on-board data logging so there is a record of what the system actually did
  • SEKO peristaltic dosing pump rated at 1.3 L/h against 3 bar — confirm the pressure at your injection point is below 3 bar and that 1.3 L/h covers your required dose
  • Self-priming pump, so it re-primes after a chemical tank change without manual bleeding
  • Black EPDM squeeze tube for better chemical compatibility and longer tube life than the previous tube material
  • Flow switch disables dosing on no-flow, so the system cannot keep injecting chemical into a stopped line
  • Fail-safe alarm relay with remote power failure detection; available as an open backboard or with a hinged lockable cabinet
  • Sizing — work out your required dose in litres per hour from the dose rate and system flow, check it sits inside the pump’s turndown range, then confirm the model’s pressure rating exceeds the pressure at the injection point

Frequently Asked Questions

How do I choose the right dosing pump?
Work out your required dose in litres per hour from the dose rate and system flow, check it sits inside the pump’s turndown range, then confirm the model’s pressure rating exceeds the pressure at the injection point. The pump in this package is rated 1.3 L/h against 3 bar.
What does the system measure and what does it control?
It measures pH continuously through the supplied probe and controls the peristaltic dosing pump to hold your setpoint, logging the result on board.
Is the control on/off or proportional?
The supplied product information does not state the control mode of the PH-XP2 in this package. We confirm it on enquiry before you order.
Are the probe and the pump included?
Yes. The pH probe, probe holder, manifold with dosing point and return to tower, SEKO peristaltic pump, flow switch and PVC backboard are all supplied as one assembly.
How is this different from just running a dosing pump?
A standalone dosing pump doses at whatever rate you set, whether the water needs it or not. This package measures pH and only doses when the reading is off setpoint, and the flow switch stops dosing when there is no flow.
What chemicals do the wetted materials suit?
The wetted path is the black EPDM squeeze tube, chosen for better chemical compatibility and longer tube life. Tell us the acid or base you are dosing and its concentration and we will confirm compatibility before you order.
What consumables does it use?
The squeeze tube is the main wearing part and is replaced periodically. The pH probe is also a consumable that needs regular calibration and eventual replacement, along with the calibration buffer solutions.
