Portable residual chlorine meter RC-31P

Introduction

The Portable residual chlorine meter RC-31P is a modern measuring device manufactured by DKK-TOA CORPORATION. Designed to meet the need for quick and accurate testing of residual chlorine content in water, the RC-31P is an ideal tool for water quality management professionals. With its advanced technology and user-friendly design, this device offers high convenience and reliability in practical applications.

Product Overview

The RC-31P stands out with its application of the advanced polarographic method, allowing for the measurement of residual chlorine without the need for any chemical reagents. This not only saves on operating costs but also eliminates the hassles associated with preparing and storing chemicals, while being environmentally friendly. The device provides high flexibility with two measurement options: a water sampling measurement type and a faucet measurement type, catering to various sampling situations. Furthermore, the RC-31P is designed with a waterproof construction meeting the IP67 standard (can be immersed in water at a depth of 1 meter for 30 minutes), ensuring durability and safety when used in wet or outdoor environments.

Key Features

• Reagent-free Method: Adopts the polarographic method, completely eliminating the need for chemicals, making measurement fast, safe, and economical.
• Flexible Measurement: Offers two measurement types: taking a water sample into a measuring cup or measuring directly from a flowing faucet, depending on the included accessories.
• IP67 Waterproof Design: Rugged housing, completely dustproof and waterproof, withstanding temporary immersion, ideal for field use.
• Instant Measurement: Suitable for quickly checking residual chlorine concentration in common water sources such as tap water and pooled water.
• Easy to Use: Simple interface, intuitive operation, requiring no complex technical skills to operate.

Technical Specifications

Applications

• Domestic Water Supply: Quickly checking residual chlorine concentration in tap water at treatment plants, distribution networks, and household faucets to ensure epidemiological safety.
• Pool Management: Continuously monitoring residual chlorine levels in swimming pool water, ensuring disinfection efficiency and swimmer safety.
• Food Industry: Testing washing water and food preparation water to ensure chlorine concentration is within permissible limits.
• Aquaculture / Aquarium: Controlling residual chlorine in supply water, as chlorine can be toxic to fish and other aquatic organisms.

Frequently Asked Questions (FAQ)

1. What are the advantages of the reagent-free polarographic method?

The biggest advantage is convenience and speed. You do not need to carry, prepare, or dispose of chemicals after measurement. This reduces operating costs, saves time, and protects the environment.

2. What is the difference between the “water sampling measurement type” and the “faucet measurement type”?

The sampling type requires you to collect water into a small measuring cup provided with the meter to perform the measurement. The faucet type has a special accessory that allows you to attach the sensor directly to a flowing faucet for continuous measurement, which is very convenient for checking at water supply points.

3. Can the RC-31P meter measure Total Chlorine?

No, the RC-31P uses a polarographic method specifically designed to measure Free Residual Chlorine. To measure total chlorine, methods that use reagents like DPD are typically required.

4. Is the meter truly waterproof? Can I drop it in the pool?

The meter is IP67 rated, meaning it is completely dustproof and can withstand immersion in water up to 1 meter deep for a maximum of 30 minutes. If you accidentally drop it into a shallow pool and retrieve it immediately, the meter will be safe.

5. Does the sensor require maintenance?

Yes, although it is reagent-free, the polarographic sensor still requires periodic maintenance (such as cleaning the electrode, replacing the membrane/electrolyte solution if applicable) to ensure accuracy. Please refer to the user manual for details.

Conclusion

The RC-31P portable residual chlorine meter from DKK-TOA is a modern measurement solution, offering maximum convenience thanks to its reagent-free technology and durable waterproof design. Whether you are testing tap water quality, managing a swimming pool, or working in the food industry, the RC-31P provides fast and reliable results right in the field.
