Ozone meter OZ-20(for liquid) / 30(for air )

Introduction

The OZ series portable ozone meters (including models OZ-20 and OZ-30) are specialized measurement devices manufactured by DKK-TOA CORPORATION. Designed to meet the growing need for ozone concentration monitoring in industrial and environmental applications, this product line offers a fast, accurate, and convenient measurement solution. With two distinct versions for liquid and gas environments, the OZ series comprehensively addresses quality control and safety requirements related to ozone.

Product Overview

The OZ series ozone meters stand out with their air calibration method, a simplified approach that saves users time and effort compared to traditional, complex calibration procedures. The devices are designed in a portable format but are still capable of performing continuous measurements, offering maximum flexibility. The product line is divided into two specialized models: the OZ-20 is optimized for measuring dissolved ozone in liquids, while the OZ-30 is designed to measure ozone concentration in the gas phase (air). Measuring with the OZ-30 is extremely simple; it only requires placing the electrode in the atmospheric environment to be measured. Both models support dual power source operation (AC and DC dry cells), ensuring high readiness in all working conditions. For the OZ-20 model, users can utilize an optional flow cell to increase accuracy when measuring dissolved ozone in flow systems.

Key Features

• Simplified Air Calibration: Utilizes an air calibration method, making the preparation of the machine before measurement quick and easy.
• Continuous Measurement: Despite being a portable device, the meter supports continuous measurement features, suitable for monitoring concentration changes over time.
• Two Specialized Versions:
  • OZ-20: Specifically used for measuring dissolved ozone concentration in liquids.
  • OZ-30: Specifically used for measuring ozone concentration in the air (Gas phase ozone).
• Easy Operation (OZ-30): Measuring ozone concentration in the air is incredibly simple, requiring only direct exposure of the electrode to the target environment.
• Flexible Dual Power: Operates on both alternating current (AC) and dry cells (DC), providing maximum convenience for both laboratory and field use.

Technical Specifications

Applications

• Water and Wastewater Treatment (OZ-20): Monitoring dissolved ozone concentration in water disinfection systems, ensuring bactericidal efficiency and controlling excess ozone.
• Food and Beverage Industry (OZ-20/OZ-30): Checking ozone concentration in food washing water (OZ-20) or monitoring ozone gas concentration used to disinfect factory spaces and storage warehouses (OZ-30).
• Medical and Pharmaceutical (OZ-30): Monitoring ozone gas concentration in clean rooms, operating rooms, or ozone sterilization equipment to ensure staff safety and sterilization effectiveness.
• Aquaculture / Aquarium (OZ-20): Controlling the amount of dissolved ozone in water to treat pathogens without causing toxicity to aquatic organisms.

Frequently Asked Questions (FAQ)

1. What is the main difference between the OZ-20 and OZ-30?

The difference lies in the measurement environment. The OZ-20 is designed with a specialized sensor to measure dissolved ozone concentration in water (liquid), while the OZ-30 uses a sensor to measure ozone gas concentration in the air (gas phase).

2. How does the “air calibration method” work?

This is a simplified method. Instead of using complex and unstable ozone standard solutions, the machine can be zero-calibrated by exposing the sensor to clean air (free of ozone). Please refer to the user manual for the detailed procedure.

3. What is the optional flow cell for the OZ-20 used for?

When measuring dissolved ozone in water, exposing the sample to open air can cause the ozone to volatilize quickly, leading to inaccurate measurement results. The flow cell is a closed measurement chamber that allows water to flow continuously past the sensor, helping to stabilize the ozone concentration in the sample and providing accurate results, especially during continuous measurement.

4. Does the OZ-30 have safety alarms when the ozone concentration in the air is too high?

Please check the detailed technical documentation or contact us to confirm the specific alarm features of the OZ-30 model, as high concentrations of ozone in the air are highly toxic to humans.

5. Can I use this meter outdoors?

Yes, the portable design and the ability to operate on dry cells (DC) make the OZ series highly suitable for taking measurements in the field or outdoor areas where power sources are not readily available.

Conclusion

The OZ-20 and OZ-30 portable ozone meters from DKK-TOA provide specialized, convenient, and reliable measurement solutions for both water and air environments. With a simple calibration method, continuous measurement capability, and flexible power options, these devices are powerful tools for quality and safety control in ozone-utilizing applications.
