GTQ-Trax20 Fixed Industrial Gas Detector – Multi-Gas Detection (Methane/CO/H2S/O2) with Catalytic/Electrochemical/Infrared Sensors, Explosion-Proof (Ex d IIC T6 Gb), 4-20mA/RS485 Output & Infrared Remote Control for Petrochemical/Chemical Plants

Explosion-Proof & Durable Design: Certified with Ex d IIC T6 Gb / Ex tD A21 IP67 T80℃ explosion-proof rating and IP67 ingress protection, suitable for harsh industrial environments (e.g., high humidity, dust, flammable areas).
Multi-Sensor Flexibility: Supports 3 sensor technologies (catalytic for flammables, electrochemical for toxic gases/O2, infrared for specific gases) to detect methane, CO, H2S, O2, and more (see Appendix 2 for full gas list).
High Accuracy & Fast Response: Alarm deviation of ±3% of the alarm point; T90 response time: ≤20s (flammables), ≤30s (O2/CO/H2S), ≤60s (other gases).
Flexible Signal Output: Offers 4-20mA analog output (compatible with DCS/PLC systems) or RS485 bus communication (for connection to KB100/KB500 control panels), with a maximum transmission distance of 1000m.
Infrared Remote Operation: Equipped with IR05 infrared remote control for safe parameter setting (low/high alarm values, zero/span calibration, address coding) without opening the detector in hazardous areas.
Intelligent Alarm System: Red/green/yellow LED indicators and 2 dry relays (K1/K2) + 1 active contact (K3) trigger alarms for low/high gas concentrations or faults, ensuring timely risk alerts.
Easy Installation: Supports wall-mounted or pipe-clamped installation; compatible with RVVP 4×0.75mm² shielded cables for secure wiring.
