Product Q&A

Q:What gases can your gas detectors detect? Can they detect multiple gases at once?

Every single gas detector are available for wide range of gases including combustible gases (methane, propane, LPG), toxic gases (CO, H2S, Cl2, NH3, SO2,O2), and VOCs. For single-gas detection, we recommend our fixed detectors with targeted sensors. If you need to detect multiple gases simultaneously, we offer multi-gas detectors or you can install multiple single-gas detectors connected to a central controller . Please contact us with your specific target gas, we'll match the right sensor.

Q:What certifications do your products have? Are they approved for international markets?

We LEL gas detector provide: ATEX (EU) and CNEx (China) explosion-proof certifications CPA (Metrological Approval) certificate CE certificate

Q:Can your 0-100% LEL wall mounted gas detector integrate with our existing control system (PLC, DCS, BMS)?

Yes, combustible gas detectors offer multiple output signal options for seamless integration 4-20mA analog signal (standard industrial protocol) Output through our controllerRS-485 Modbus for digital communication and remote monitoring Relay contacts (dry contacts) for direct control of alarms, fans, or solenoid valves

Q:What's the IP rating?

Standard models: IP65 (dust-tight and protected against water jets) They are designed to operate in -20C to +50C temperature ranges and environments, making them suitable for outdoor installations, chemical plants

Q:What are the available detection principles for this device?

The gas detector supports three detection methods: catalytic combustion, semiconductor, and infrared (IR) sensing technologies, offering flexibility and high accuracy depending on the application.
