Low concentration portable dissolved oxygen meter DO-32A

Introduction

The Low concentration portable dissolved oxygen meter DO-32A is a specialized analytical device manufactured by DKK-TOA CORPORATION. Specifically designed to accurately measure dissolved oxygen at extremely low concentrations, the DO-32A is an indispensable tool in industrial applications that demand strict water quality control. With its high response and accuracy, this device ensures absolute reliability in monitoring sensitive water systems.

Product Overview

The DO-32A stands out with its flexible measurement capabilities, covering a wide range from trace levels (μg/L or ppb) up to 20mg/L (ppm). The auto-range feature supports continuous measurement without manual intervention, optimizing the monitoring process. The device utilizes a compact flow cell, making operation and maintenance extremely easy. Notably, the DO-32A offers maximum convenience with its dual power supply capability: using AC power for stationary work or dry cells (DC) for mobile applications, ensuring the device is always ready for operation in any situation.

Key Features

• Accurate Low Concentration Measurement: Provides high response and accurate measurement from μg/L (ppb) order up to 20mg/L (ppm).
• Auto-range Support: Supports continuous measurement by automatically switching between 4 different ranges for optimal results.
• Compact Flow Cell: The small flow cell design makes the device easy to operate, clean, and maintain.
• Flexible Dual Power Supply: Convenient operation with both AC and DC (dry cell) power supplies, suitable for both stationary and mobile use.
• Ideal for Boiler Water: Specifically designed for checking and managing water supply systems for high-pressure boilers, where dissolved oxygen can cause severe corrosion.

Technical Specifications

Applications

• Boiler Water Management: The most critical application is checking and monitoring dissolved oxygen in feed water for high-pressure boilers to prevent corrosion of pipes and equipment.
• Power Plants: Monitoring ultrapure water quality in thermal power cycles.
• Semiconductor Industry: Controlling dissolved oxygen in deionized (DI) water used in microchip manufacturing processes.
• Aquaculture / Aquarium: Although specialized for low concentrations, it can measure up to 20mg/L, useful in in-depth aquatic environmental research.

Frequently Asked Questions (FAQ)

1. What is the lowest dissolved oxygen concentration the DO-32A can measure?

The DO-32A is specifically designed for low concentration measurement, capable of accurately measuring at trace levels with the lowest range being 0.00 – 19.99 μg/L (ppb).

2. How does the “Auto-range” feature work?

The Auto-range feature allows the meter to automatically detect the oxygen concentration in the sample and switch between 4 measurement ranges (from μg/L to mg/L) to display the result with the best resolution without the user having to manually select the range.

3. Why does the meter use a Flow cell?

For measuring dissolved oxygen at extremely low concentrations (ppb), exposing the sample to air will immediately skew the results. The flow cell allows water to flow continuously past the sensor in a closed system, ensuring absolute accuracy.

4. Can the meter be used in the field?

Yes, the DO-32A is a portable device and supports a dual power supply. You can use dry cells (DC) to take the meter directly to the field or various sampling locations within a plant.

5. What is the primary application of this meter?

The primary and most important application of the DO-32A is checking and managing the feed water systems for high-pressure boilers, where controlling dissolved oxygen at ppb levels is mandatory to prevent corrosion.

Conclusion

The DO-32A low concentration portable dissolved oxygen meter from DKK-TOA is a professional measurement solution, delivering superior accuracy for demanding industrial applications. With its ppb-level measurement capability, closed flow cell design, auto-range feature, and flexible power supply, the DO-32A is the perfect tool for protecting high-pressure boiler systems and monitoring ultrapure water quality.
