Online Dissolved Oxygen Controller

Introduction

An online dissolved oxygen controller monitors and regulates oxygen levels in liquids. It is widely used in wastewater treatment and aquaculture. It solves oxygen fluctuation problems and ensures stable process control.

Standards

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

JJF 2294-2025-Calibration specification for on-line low-level dissolved oxygen meters

IEC 60746-4:2018-Expression of performance of electrochemical analyzers-Part 4: Dissolved oxygen in water

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

Features

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

2. Multiple measurement modes cover a range of applications.

3. Automatic temperature compensation reduces measurement error.

4. Water-resistant, portable design suits field and bench use.

5. Stable readings with drift indicators support confident results.

FAQ

What is the Online Dissolved Oxygen Controller mainly used for?

The Online Dissolved Oxygen 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 Dissolved Oxygen 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 Dissolved Oxygen Controller?

A 12-month warranty applies to the complete equipment against defects in materials and workmanship. It excludes consumables, wearing components and accidental or misuse damage. Our service team handles claims against the serial number, and longer cover can be arranged.

Will staff need special training?

No advanced specialist skills are needed for standard operation, though correct sample handling and safety practice should be followed. We supply a detailed manual and start-up support. For multi-user or regulated sites, a short staff training session can be arranged.

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 Dissolved Oxygen Controller need calibration or verification?

Factory calibration is included, and routine verification is recommended every 6 to 12 months using suitable reference materials. Regulated sites may require more frequent checks and documented records. Calibration support and certificates can be provided on request.

Are consumables and spare parts easy to obtain?

No proprietary consumable contract is required; standard parts are available from us and common laboratory suppliers. Our service team can supply a recommended parts list for the model. Most routine spares are held for quick delivery.

Can it be adapted to our requirements?

The standard model can be configured with selected accessories and operating options to suit the task. Non-standard requests are assessed before quotation so the final build is clearly defined. We confirm details before production.

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 maintenance and safety points matter?

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.
