The online gas detector from Qi'an Technology uses imported intelligent gas sensors, and is a high-performance intelligent detection instrument that can continuously monitor combustible gases online.
The detector features an overall explosion-proof structure, with high sensitivity and accuracy. Through the gas alarm controller and monitoring management software, real-time concentration display can be achieved on a computer. It can also transmit real-time monitoring data and alarm status to the safety control center via an optional wireless module. It is widely used in industries such as petroleum and petrochemical, metallurgy, environmental protection, gas, fire protection, municipal engineering, chemical industry, shipbuilding, electric power, process control, sewage treatment, and emergency rescue monitoring.
Main Features:
◆ Imported high-performance sensor, with high measurement accuracy, good repeatability and long service life;
◆ Adopts an independent 16-bit AD chip and 4-layer circuit board design, with stronger anti-interference ability for weak signals;
◆ Dashboard-style display interface, with an elegant and user-friendly design;
◆ Multiple units available: mg/m3, ppm, VOL, LEL;
◆ Embedded 32-bit ultra-low-power processor, paired with a unique signal processing algorithm, ensuring fast response and stability;
◆ Automatic protection function against high-concentration gas impact, with factory reset function to prevent misoperation;
◆ Equipped with an infrared remote controller, allowing operation without opening the device, simple and convenient;
◆ Optional 3-wire 4～20mA, RS485 signal output, and relay output;
◆ Two cable entry ports, facilitating on-site installation;
◆ First-class mechanical design, with the gas chamber made of military-grade high-strength aluminum alloy, wear-resistant and corrosion-resistant, suitable for complex and harsh industrial environments. The rational and scientific gas chamber design ensures the accuracy of real-time sensor monitoring;
◆ Explosion-proof grade: Exd II CT6, certified by the National Center for Explosion-proof Electrical Inspection
