Fixed Chlorine Dioxide (ClO2) Gas Detector, 0 to 1/5/10/20/50/100 ppm

Fixed Chlorine Dioxide gas detector is equipped with sound & light alarms to notify workers of dangerous ClO2 gas levels, allowing them to take immediate action to mitigate risks and ensure the safety of personnel and the surrounding environment.

Features

• Fixed ClO2 gas detector adopts high precision sensor for accurate gas leak detection.
• Chlorine Dioxide detector is equipped with 3-wire system 4-20mA analog output, relay output, RS485 output (optional).
• The Chlorine Dioxide gas monitor is compatible with various controlled alarms, PLC, DCS and other control system, and can be remote monitored.
• Explosion-proof design, fast, relaible and stable.
• Infrared ray controller can remote control the alarm point settings, zero calibration, and address modification.
• Two-stage alarm with sound and light, and the alarm point is settable.
• The industrial ClO2 gas detector has self-calibration function, and three standard keys will be used to realize on-site maintenance.
• Fixed ClO2 gas detector can output one or two on-off signals, can drive ventilator, solenoid valve or other external devices.

Notes

Regarding the flow rate for gas detectors, there are 2 types:

• Pump-Suction Type: Equipped with a built-in pump, with a flow rate of 600 mL/min. (Models: GD200, GD400, GD600)
• Diffusion Type: Not equipped with a built-in pump, with a flow rate of 300 mL/min. (Models: GD300, GD500, GD800)

If you require a customized flow rate, please let us know your specific requirements. We will evaluate whether customization is possible. A flow rate that is too high or too low can affect measurement accuracy, so we recommend using an appropriate flow rate for your application.

Flow rate only needs to be considered when sampling gas from pipelines. For measuring gas concentrations in normal ambient air, you do not need to consider the flow rate. To measure confined spaces such as pipelines, please get in touch with us and provide the detailed conditions of use.

Installation Guide

The following precautions apply when connecting the GD300 series fixed gas detector to a pipeline:

1. Working pressure should be stable at 1 bar ±10%, and the flow rate should be controlled at 300 mL/min.
2. Working temperature is -20°C to +50°C.
3. Working humidity is 0–95% RH. When the humidity is above 60% RH, it is recommended to use a dehumidifier or add a filter. When the humidity is above 95% RH, the gas is essentially saturated with water, making measurement impossible.
4. The gas detector should be installed indoors. If it is installed outdoors, a rain cover should be added to protect the entire instrument.
5. For the second pipeline connection method of the GD300 gas detector, the pipe-mounted installation, the detector mounting thread size is M45 × P2.0. During installation, hold the detector with both hands, keeping the sensor parallel to the mounting thread. Align it with the threaded port, rotate the detector clockwise, and install it in the desired position. To prevent gas leakage at the threaded connection, an appropriate amount of thread seal tape can be wrapped around the sensor head thread before installation.

Tips: What is Chlorine Dioxide (ClO2) and why is it important to detect it?

Chlorine Dioxide gas is a yellow to reddish-yellow gas with a Chlorine-like odor, used primarily as a disinfectant and bleaching agent. It is effective in killing bacteria, viruses, and some types of parasites, making it crucial in water treatment, food processing, and healthcare settings. Detecting ClO2 is essential because of its dual nature: while beneficial in controlled amounts, it poses health risks at high concentrations, including respiratory irritation and oxidative damage. Monitoring ClO2 levels ensures safe usage, protects public health, and complies with environmental regulations. Effective detection helps maintain the delicate balance between its beneficial disinfectant properties and its potential toxicity, ensuring safe and efficient use in various applications.
