Online pH Controller

Introduction

An online pH controller continuously monitors and adjusts pH levels in industrial and laboratory systems. It is widely used in water treatment and chemical processes. It solves manual pH control limitations and ensures stable process conditions.

Standards

GB/T 11165-2005-Laboratory pH meter

IEC 60746-1:2003-Expression of performance of electrochemical analyzers-Part 1: General

USP General Chapter <791>-pH

IEC 60746-2:2003-Expression of performance of electrochemical analyzers-Part 2: pH value

Complies with the above standards, but is not limited to them.

Features

1. Replaceable electrodes and probes suit different parameters.

2. Automatic temperature compensation reduces measurement error.

3. Stable readings with drift indicators support confident results.

4. Multiple measurement modes cover a range of applications.

5. Clear display shows readings, temperature and calibration status.

FAQ

What is the Online pH Controller mainly used for?

The Online pH Controller is used to measure electrochemical properties such as pH, conductivity, dissolved oxygen or ion concentration. It supports water treatment, environmental monitoring, chemical, pharmaceutical, food and research laboratories.

Which standards and regulations apply to the Online pH Controller?

The meter is designed with reference to IEC 61010 electrical safety and relevant GB/T standards for electrochemical measurement, with procedures following applicable standard methods and buffer systems. Compliance documentation can be provided on request.

What warranty comes with the Online pH Controller?

The complete unit carries a 12-month warranty from delivery, covering the main body, core components and controller against manufacturing defects. Consumables and wearing parts such as filters, seals and probes are not covered. Damage from misuse, improper power or unauthorised repair is excluded, and extended warranty can be quoted.

Is the Online pH Controller difficult to operate?

Routine operation is straightforward and is covered in the user manual, including setup, daily use and basic maintenance. Staff with basic laboratory experience can run it after a short familiarisation. We provide remote guidance and can arrange on-site training where required.

What is the typical lead time for order delivery?

Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Does the Online pH Controller need calibration or verification?

To protect result reliability, periodic verification should be performed, typically once or twice a year. The instrument arrives factory-calibrated, and self-check routines help spot drift. We offer traceable calibration service if the site needs it.

Are consumables and spare parts easy to obtain?

Filters, seals, probes and similar items are standard and can be supplied through our channel. Customers may also source equivalent items that meet the specification. Provide the model and serial number to confirm compatibility before ordering.

Are options or configurations available?

Yes, common options include different ranges, voltages, accessories, interfaces and capacity or size configurations. We confirm feasibility, specifications and any delivery impact before order confirmation. Custom requirements are reviewed case by case.

Is installation and commissioning included?

Most models can be commissioned by following the manual, including positioning, connections, checks and a first test run. Remote guidance is available during start-up. On-site installation, commissioning and training can be arranged separately where required.

What should be avoided when using the Online pH Controller?

Do not let the electrode dry out, measure outside the rated range or store probes incorrectly. Rinse and condition electrodes and calibrate regularly. Follow the operating instructions.
