Fixed Benzene (C6H6) Gas Detector, 0 to 10/100/200/1000/10000 ppm

ATO fixed Benzene (C6H6) gas detector adopts advanced sensor technology, which can continuously detect the surrounding air for traces of Benzene vapor. Upon detecting benzene levels above a predetermined threshold deemed safe, this gas monitor triggers sound & light alarm to alert personnel, allowing for timely evacuation or remedial action.

Features

• Fixed C6H6 gas detector adopts high precision sensor for accurate gas leak detection.
• Benzene gas detector is equipped with 3-wire system 4-20mA analog output, relay output, RS485 output (optional).
• The Benzene 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 C6H6 gas detector has self-calibration function, and three standard keys will be used to realize on-site maintenance.
• Fixed Benzene gas detector can output one or two on-off signals, can drive ventilator, solenoid valve or other external devices.

Specification

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: Where is Fixed Benzene (C6H6) gas detector used?

Fixed benzene (C6H6) gas detectors are commonly used in environments where Benzene gas concentration needs to be monitored. C6H6 gas is a common volatile organic compound commonly found in industrial production, chemical laboratories and certain production processes. Benzene is a harmful chemical and long-term exposure can cause health problems, including respiratory problems and potential cancer risks.

Therefore, fixed C6H6 gas detectors are usually installed in factories, chemical plants, laboratories, petroleum processing plants and other places, as well as in some production processes that require Benzene handling. These detectors can monitor the concentration of C6H6 gas in a timely manner to ensure that the working environment meets safety standards, and can sound an alarm when gas leaks or the concentration exceeds the standard so that timely measures can be taken to protect the health and safety of workers.
