Industrial & Commercial Point-Type Combustible Gas Detector Factory Direct for Canada

%LEL represents the volume concentration of a combustible gas required to sustain ignition in air. For Methane (CH4), 100% LEL corresponds to 5.0% volume in air (50,000 ppm). Point-type combustible gas detectors monitor safety thresholds in %LEL (typically alarming at 20% to 40% LEL), whereas ppm-level sensors are reserved for toxic gas monitoring or trace environmental sniffers.

Mounting height is governed strictly by the vapor density of the target gas relative to air (air = 1.0). Natural gas (predominantly Methane, vapor density ~0.55) is lighter than air and rises; detectors must be mounted within 30 cm (12 inches) of the ceiling. Propane (vapor density ~1.55) is significantly heavier than air and sinks; detectors must be positioned within 30 cm of the finished floor, away from direct draft channels.

Yes. Shield industrial detectors are built with internal thermal compensation matrixes. The sensing heads are operational between -40°C and +70°C. For extreme arctic conditions, specialized firmware activates continuous internal pellistor circuit stabilization to prevent cold-drift false triggering.

Yes. With 18+ years of dedicated gas instrumentation manufacturing, our Chengdu factory supports comprehensive OEM/ODM contracts: custom casting logos, powder-coated enclosures, specialized RS485 Modbus register mapping, custom alarm setpoints, and packaging tailored for Canadian engineering distribution channels.

Stand-alone units (such as the SD2130 series) contain internal relays, audible buzzers, and flashing visual strobes on the unit itself. In localized applications such as commercial kitchens or small standalone compressor rooms, this eliminates the cost and wiring footprint of a remote master control panel, while directly driving solenoid cut-off valves.
