Fixed Gas Detector with Pump, Multi Gas Detection Alarm – GAOTek

Description Overview The GAOTek Fixed Gas Detector ensures real-time monitoring of up to six gases with high precision and quick response. Its built-in suction pump provides faster and more accurate readings than diffusion models. Equipped with a 2.4-inch color LCD display, it supports multiple output signals for remote monitoring. Weighing 3.4kg (7.49 lbs), this durable detector is designed for harsh industrial environments.   Features Built-in suction pump for fast and accurate detection. Simultaneously detects up to 6 different gases. Supports ppm, mg/m³, μmol/mol units with automatic conversion. 4-inch HD LCD display with wide viewing angle (120°). Strong anti-interference design ensures stable performance in harsh environments. Multiple transmission signals: 4-20mA, RS485, relay, wireless (optional). Remote control via infrared remote for settings adjustment. Sound & light alarm for enhanced safety alerts. Optional accessories: dry filter device, pretreatment system, high-temp probe, control panel.   Technical Specifications Network Frequency 2.4G high frequency Detected Gas CO, H2S, O2, CH4/Combustible Gases, customizable Detection Principle Electrochemical, Catalytic combustion, Infrared Ray, PID (based on gases) Measure Range CO: 0-1000/2000ppm; H2S: 0-100/200ppm; O2: 0-25%/30%VOL; CH4/EX: 0-100%LEL/100%VOL Resolution CO: 1ppm; H2S: 0.01ppm; O2: 0.01%VOL; CH4/EX: 1%LEL/1%VOL Accuracy ≤±2-3% F.S.
