Explore our factory-direct gas safety equipment, designed for seamless integration into industrial monitoring, residential protection, and commercial building systems.
From indoor air quality mandates to industrial leak safety, carbon dioxide detection is now mission-critical for modern building management, agriculture, and global industrial manufacturing.
Modern commercial buildings leverage real-time CO2 monitoring to dynamically throttle HVAC fresh air dampers. By optimizing ventilation based on human occupancy rather than fixed schedules, facility managers reduce HVAC energy consumption by up to 35% while maintaining compliance with ASHRAE Standard 62.1.
Carbon dioxide is an odorless, colorless toxicant at elevated levels. High concentrations displace oxygen and pose immediate hazards. Regulatory authorities (OSHA, NIOSH, EN 50543) enforce strict limit values: 5,000 ppm TWA (Time-Weighted Average) and 30,000 ppm STEL (Short-Term Exposure Limit) in industrial cellars, breweries, and food processing units.
In Controlled Environment Agriculture (CEA), carbon dioxide enrichment is vital for maximizing photosynthetic productivity. Maintaining CO2 concentrations between 800 ppm and 1,200 ppm boosts crop yield by 20–30%. Precision sensing prevents both carbon starvation and photosynthetic saturation.
Achieving long-term stability and immunity to cross-sensitivity requires selecting the optimal optical and chemical sensing topology for your application environment.
NDIR sensors operate on the Beer-Lambert law, measuring gas concentration through the attenuation of specific infrared light wavelengths. CO2 molecules absorb infrared radiation specifically at 4.26 micrometers (μm).
Our dual-beam NDIR architecture utilizes a primary measurement optical channel alongside an unabsorbed reference channel (3.91 μm). This dual-wavelength setup automatically compensates for light source aging, dust accumulation, and optical chamber degradation, ensuring operational stability over 15+ years without zero-point calibration drift.
Photoacoustic technology pulses mid-infrared light into a microscopic acoustic chamber. As CO2 molecules absorb light energy, they generate localized thermal expansion, producing periodic pressure waves (sound) detected by a micro-electromechanical microphone (MEMS).
PAS allows extreme miniaturization—up to 75% smaller than traditional optical NDIR chambers—making it ideal for compact IoT smart home devices, desktop indoor air quality monitors, and low-power HVAC room transmitters.

From single-chip OEM sensor integration to explosion-proof transmitter arrays, our CO2 detection hardware guarantees sub-second responsiveness and rock-solid reliability.
Integrated via BACnet MSTP or Modbus RTU into Building Management Systems (BMS). Our wall-mount and duct-mount CO2 sensors continuously analyze return air quality, modulating fresh air supply to maintain CO2 under 800 ppm while optimizing fan energy usage in schools, office towers, and medical facilities.
With global transitions toward natural refrigerants, R744 (CO2) is replacing HFCs in supermarket refrigeration racks and cold storage vaults. High-pressure leaks present acute asphyxiation risks. Our IP65 explosion-proof CO2 transmitters provide instant localized alarms, activating emergency exhaust fans and shut-off valves.
In medical research and cell culture incubators, precise 5.0% CO2 control is crucial for maintaining physiological pH in liquid growth media. Our high-concentration NDIR modules feature heated optical cavities to eliminate condensation risks in 95% relative humidity environments.
In humid or corrosive gas deployment zones, standard aluminum sensor chambers tarnish, leading to optical reflection losses. Our high-grade NDIR modules utilize electroplated 24K gold mirror optical chambers, guaranteeing zero corrosion and superior reflectivity across multi-year operational cycles.
Behind our high-volume output is a rigorous quality control framework engineered to eliminate early-life failure and guarantee absolute measurement repeatability.
Every sensor batch undergoes 72 hours of continuous thermal stress cycling (-20°C to +60°C) within automated climatic chambers. Temperature coefficients are individually mapped into on-chip non-volatile EEPROM memory to guarantee flat thermal response curves across extreme operational ranges.
Calibration relies on certified reference gas mixtures (99.999% pure Nitrogen zero-gas, alongside 1,000 ppm, 5,000 ppm, and 20,000 ppm certified CO2 standards). Digital high-precision mass flow controllers (MFCs) automate multi-point concentration calibration, eliminating human operator error.
Deploying gas safety systems requires meeting strict regional building standards and electrical explosion-proof directives.
All CO2 sensing modules and industrial transmitters are fully certified under European Electromagnetic Compatibility (EMC) Directive 2014/30/EU and RoHS lead-free hazardous substance restrictions.
For chemical manufacturing facilities, gas vaults, and hazardous zones, our heavy-duty CO2 detectors feature flameproof cast-aluminum enclosures certified for Zone 1 and Zone 2 explosive environments.
Designed to help project owners satisfy target requirements for LEED v4.1, WELL Building Standard v2, and RESET Air indoor environmental quality compliance credits.
Our engineering team is actively advancing gas detection capabilities toward lower power draw, smaller footprints, and enhanced edge AI processing.
Leveraging high-efficiency MEMS infrared light sources and pulsed power drivers, our upcoming ultra-low power sensor engines reduce average current consumption below 50 μA, enabling 10-year battery lifespans in wireless LoRaWAN and NB-IoT environmental monitors.
On-chip machine learning models analyze long-term ambient pressure, temperature drift, and occupancy profiles. The sensor automatically filters out sudden atmospheric pressure drops (e.g., passing storm fronts) to eliminate false baseline recalibrations.
Integrating dual optical filters into a single NDIR cavity allows simultaneous real-time detection of Carbon Dioxide (CO2) and Methane (CH4) or Refrigerants (R744/R1234yf) in a single compact module.
