Combine Gas Detectors

Ideal for confined spaces, industrial inspections, and plant safety — these detectors reduce the need for multiple instruments while improving safety efficiency.

New Cosmos Electric’s Combined Gas Detectors are engineered to monitor multiple gas hazards at once, providing real-time alerts for combustible gases, oxygen deficiency, hydrogen sulfide, and carbon monoxide in a single device. 

Explosion-proof and built for field durability, these devices help protect workers from multi-gas risks in one simple-to-use solution.

XA-4400II

A wearable, explosion-proof multi-gas detector capable of monitoring up to four gases simultaneously: combustible gas, oxygen, hydrogen sulfide, and carbon monoxide. Users can select 2 to 4 gas types based on their specific safety requirements. The unit features a 3-year sensor life and is designed for everyday worker protection in industrial environments.  

  • Gases Detected:  Combustible gases, Oxygen, H₂S, CO (2–4 gases selectable)
  • Explosion Proof: Yes
  • Sensor Life: Approx. 3 years (annual inspection recommended)
  • Applications: Confined space entry, oil & gas, chemical plants, emergency response

XP-302M

A multi-gas detector designed to simultaneously measure four gases: oxygen, combustible gas, hydrogen sulfide, and carbon monoxide. Built with a sensor unit replacement system that reduces maintenance time and costs, the XP-302M features large, clear alarms — both visual and audible — to ensure immediate hazard recognition.

  • Gases Detected: O₂, Combustible Gas, H₂S, CO
  • Detection Method: Simultaneous multi-gas monitoring
  • Features: Replaceable sensor unit, large buzzer and lamp alarm
  • Applications: Industrial safety inspections, confined spaces, gas leak detection​


XP-3318II

A portable gas detector designed for simultaneous detection of combustible gases (LEL level) and oxygen concentrations. This explosion-proof model is equipped with Bluetooth for real-time data transfer to smartphones and tablets, plus automatic email alerting when alarms are triggered.

  • Gases Detected: Combustible gases (LEL), Oxygen
  • Explosion Proof: Yes
  • Connectivity: Bluetooth and email notification
  • Applications: Leak detection, confined spaces, safety inspections
