Qian'an Techs online gas detector uses imported intelligent gas sensors, it is an intelligent high-performance detection instrument that can continuously monitor combustible gas online.
The detector has an overall flameproof structure, with high sensitivity and accuracy. Through the gas alarm controller and monitoring management software on the computer, the detector can realize real-time concentration display; the optional wireless module can also transmit real-time monitoring data and alarm status to the safety control center. 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, emergency rescue monitoring, etc.
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 display interface design, with beautiful and readable readings, reflecting humanized details;
◆ Multiple units available: mg/m3, ppm, VOL, LEL;
◆ Uses an embedded 32-bit ultra-low-power processor, combined with a unique signal processing algorithm, with fast response and stability;
◆ Automatic protection function against high-concentration gas impact, with factory reset function to prevent misoperation;
◆ The instrument is equipped with an infrared remote controller, which is operated without opening the cover, simple and convenient;
◆ Optional 3-wire 4～20mA, RS485 signal output, and relay output;
◆ Two cable entry ports, convenient for on-site installation;
◆ First-class mechanical design, the gas chamber uses military-grade high-strength aluminum profile, wear-resistant and corrosion-resistant, suitable for complex and harsh industrial environments; the reasonable and scientific gas chamber design ensures the accuracy of real-time sensor monitoring;
◆ Explosion-proof grade is Exd II CT6, certified by the National Explosion-proof Electrical Inspection Center
