Product Description Product Description4 in 1 Multi Gas H2s Ex Co O2 Fixed LPG Gas Detector >>OverviewEquipped with original imported intelligent gas sensors, this is a high-performance intelligent detection instrument capable of continuous online monitoring of multiple gases. The detector features an integral explosion-proof structure with high sensitivity and precision. Real-time gas concentration data can be displayed on a computer through a gas alarm controller and monitoring software. Additionally, optional wireless modules enable real-time transmission of monitoring data and alarm statuses to safety control centers. It is widely applicable across industries such as petroleum/petrochemicals, metallurgy, environmental protection, gas, fire safety, municipal services, chemical engineering, shipbuilding, power generation, process control, wastewater treatment, and emergency rescue monitoring. >>Features○ Original imported high-performance sensors with high measurement accuracy, excellent repeatability, and long service life.○ 16-bit AD chip and 4-layer PCB design ensure enhanced weak signal processing and superior anti-interference capabilities.○ Dashboard-style display interface with clear, elegant readings and user-friendly design details.○ Multiple unit options: mg/m3, ppm, VOL, and LEL.○ Embedded 32-bit low-power processor paired with proprietary signal processing algorithms for fast response speed and high stability.○ Auto-protection against high-concentration gas impact, factory reset function, and misoperation prevention.○ Built-in infrared remote control for easy operation without opening the housing.○ Configurable outputs: three-wire 4-20mA, RS485 signal, and relay output.○ Dual cable entry ports for convenient on-site installation.○ Robust mechanical design: Gas chamber made of high-grade aluminum alloy profile ensures wear-resistant, corrosion-resistant performance in harsh industrial environments. Scientifically optimized gas chamber design guarantees real-time monitoring accuracy.○ Explosion-proof certification: Exd II CT6, certified by the National Explosion-Proof Electrical Product Testing Center. >>Main technical parameters Detection PrincipleElectrochemical principle, Infrared principle, Catalytic combustion principleMeasuring RangeH2S: 0-100 ppm; CO: 0-1000 ppm; O2: 0-25% VOL; Ex: 0-100% LEL (other gases customizable)Resolution0.01, 0.1, 1Sampling MethodFree diffusion type - Online continuous detection with free diffusion method.Installation MethodWall-mounted; Pipeline-mounted (clamp-on or insertion type, with external threads)Indication Error≤±1% F.SRepeatability≤±1% (F.S/year)Zero Drift≤±1% (F.S/year)Response Time≤20 seconds (T90) (higher requirements depend on sensor performance)Recovery Time≤10 seconds (T90) (higher requirements depend on sensor performance)Power Supply12-30 VDCPower Consumption≤2.5 W (at DC24V)Environmental Pressure80 kPa ~ 120 kPaEnvironmental Temperature-20°C ~ +60°C (typical); -40°C ~ +80°C (extreme)Environmental Humidity10%~95% RH (non-condensing)Main MaterialADC12 aluminum alloy housing with PTFE coating (wear-resistant and corrosion-resistant)Output SignalThree-wire 4-20 mA current signal output (compatible with alarm controllers)Signal TransmissionShielded three-core (or four-core) cable; maximum transmission distance: 1000-2000 metersAlarm MethodAudible and visual alarm (optional, alarm sound <90 dB)Direct ReadingMeasured value, max/min valuesData DownloadRS485 serial port for data exportCalibration2-4 point calibration; customizable calibration valuesExplosion-proof Electrical1.
