Fixed benzene (C₆H₆) gas detector is designed for accurate gas leak detection using a high-precision sensor for fast and reliable measurements. This industrial-grade detector offers a wide detection range (0-1ppm to 0-10000ppm) to suit various applications, including chemical plants, refineries, and laboratories.
Anti-magnetic interference
- The fixed benzene gas detector can resist the strong magnetic interference of 15V/meter.
- In areas with dense magnetic products or dense electronic products, such as tunnels, mines, confined spaces, etc., the data is guaranteed to be stable and reliable.
Using high-precision sensors
- The fixed C6H6 gas detector is equipped with an infrared remote control as standard, which can realize the functions of alarm point setting, zero point calibration, and address modification without opening the cover.
- Compatible with various control alarms, PLC, DCS and other control systems to realize remote monitoring.
Variety of installation methods
- Wall mounted type, installed on the wall directly, real time monitoring.
- Piping type, installed on the pipeline, monitoring the gas concentration inside.
- Flow type, connected with external sampling pump and tube, measure the gas concentration in enclosed space.
Applications
The fixed benzene (C₆H₆) gas detector is widely used in chemical plants, petrochemical industries, pharmaceutical factories, laboratories, oil refineries, painting workshops, and storage facilities for real-time benzene leakage monitoring and industrial safety protection.

SISCO Gas Detector Catalogue.pdfQ1: What is a fixed gas detector?
A1: The fixed gas detector is composed of sensors and transmitters, and is installed at the detection site. The secondary instrument consisting of circuit, power supply and display and alarm device is installed in a safe place, which is convenient for staff to monitor. In industrial installations and production processes, fixed gas detectors are generally used, because fixed gas detectors can be installed at specific detection points to detect specific gas leaks.
Q2: What does a gas detector detect?
A2: Combustible gases: Natural gas (methane), liquefied gas, coal gas (hydrogen), acetylene, pentane, alkynes, acetone, toluene, alcohols, hydrocarbons, light oil, etc.
Toxic gases: Carbon monoxide, hydrogen sulfide, ammonia, chlorine, oxygen, phosphine, sulfur dioxide, hydrogen chloride, chlorine dioxide and other toxic and harmful gases.
Q3: Difference between fixed gas detector and portable gas detector
A3: The biggest advantage of fixed gas detectors is 24-hour uninterrupted measurement. As long as the power is turned on, the fixed gas detector is in normal detection work. Portable gas detectors are usually used in confined spaces and confined spaces, but the gas environment in these spaces is usually very complex, and there will be situations such as lack of oxygen and high concentrations of harmful gases.
Tips:Â Where should I install the fixed benzene gas detector?
A fixed benzene gas detector should be installed near potential sources of benzene, such as chemical processing areas, storage zones, or ventilation exhausts. Since benzene is slightly heavier than air, it tends to accumulate near the ground, so the detector should be installed about 30–60 cm (12–24 inches) above the floor.
The installation site should be free from excessive moisture or corrosive environments and should allow easy access for maintenance and calibration. Avoid placing the detector near ventilation sources or in corners to ensure accurate gas detection and proper airflow.
