The GTYQ-MIC-600-IR2 is a Dual Optical Path Infrared Combustible Gas Detector that utilizes the 4.65 μm infrared absorption wavelength of methane to detect hydrocarbons, VOCs, and flammable vapors. It features dual-light-source redundancy with automatic failover in the event of a single-light-source failure, and the sensor has a service life of up to 10 years. The entire unit is equipped with a dual-heating structure for both the main unit and the sensor, making it suitable for extreme operating conditions such as low temperatures, high humidity, high dust levels, and large temperature differentials. It supports three detection modes—diffusion, flow-through, and duct—and can provide 24-hour online monitoring of combustible gas leaks and concentration exceedances. The Dual Optical Path Infrared Combustible Gas Detector is widely used in industrial settings such as RTO furnaces, petroleum, chemical, gas, metallurgy, and hazardous chemical storage facilities. It complies with multiple national explosion-proof and detection standards, including GB12358-2024, and holds a full suite of compliance certifications for CPA metrology, explosion-proof safety, and ISO standards.

Stable and Durable Optical Path and Hardware: The open-path gas chamber made of 316L stainless steel minimizes moisture and dust buildup, simplifying maintenance; Dual redundant light sources, combined with automatic zero-point tracking and multi-level calibration, ensure no data drift over long-term use; the entire unit features constant-temperature heating to eliminate interference from low-temperature condensation; explosion-proof rating: Ex db IIC T6 Gb; IP66 protection (upgradable to IP67); optional cast aluminum or stainless steel housing, with vibration and static resistance.
Convenient and safe on-site operation: The Dual Optical Path Infrared Combustible Gas Detector supports three operation methods—four buttons on the unit, a 15-meter infrared remote control, and magnetic rod touch control—allowing for commissioning in hazardous areas without opening the cover; a 2-inch color LCD screen displays real-time concentration, trends, and peak values; an optional LED segment display is available; the interface is bilingual (Chinese and English); and units can be freely switched between % Vol, % LEL, and ppm.
Multiple signal outputs support remote intelligent management: Standard configurations include 4–20 mA, relay switching, and RS485 signals; optional Hart, LoRa/4G/NB-IoT wireless transmission is available. The device supports remote maintenance, remote upgrades, and data recovery. With built-in storage for over 200,000 records—viewable and exportable locally—it enables the establishment of a comprehensive gas monitoring network across the entire facility.
Tiered intelligent alarms and multi-level protection: The Dual Optical Path Infrared Combustible Gas Detector supports multi-level alarms including low, high, range, and TWA/STEL thresholds, distinguishing between fault and concentration alarms, with customizable alarm volume and frequency; Built-in false-trigger detection; detection accuracy ≤ ±2% FS; T90 response time ≤ 4 seconds; recovery time ≤ 5 seconds; measurement range covers 0–100% LEL, 0–5% Vol, and 0–10,000 ppm.
Power supply: DC 12–36 V (standard 24 V); operating temperature range: –40°C to 80°C (customizable low-temperature version down to –60°C); optional modules include temperature and humidity sensors, wireless communication, and TCP/IP network modules; accessories include a magnetic rod, audible and visual alarms, a 24 V power supply, and host computer monitoring software; total unit weight is approximately 2.5 kg; electrical interface specifications can be customized as needed.
The Dual Optical Path Infrared Combustible Gas Detector is suitable for industrial facilities where there is a risk of combustible hydrocarbon or VOC gas leaks, including petroleum refining and chemical processing plants, RTO exhaust gas treatment systems, gas stations, metallurgical manufacturing, hazardous chemical storage facilities, new energy facilities, and pharmaceutical plants.
