Industrial safety leaves nothing to chance. Gas detection is the first line of defense in safeguarding lives and assets. For over two decades, Nuoan Technology has been at the forefront of gas sensing and detection analytics. As a nationally certified “Little Giant” enterprise — recognized for specialization, precision, differentiation, and innovation — we drive industry advancement through relentless innovation and foster healthy market growth through strict regulatory compliance.
Our new national standard-compliant portable gas detector series is now officially available and will make its debut at the upcoming China International Measurement Control and Instrumentation Exhibition (MICONEX). Engineered for the oil & gas, chemical, metallurgy, and power sectors, these solutions provide convenient, accurate, and dependable gas detection that industry professionals can trust.
1、Single-Gas Portable Detector: Precision, Portability, and Peak Efficiency
For targeted detection of specific gases, the Nuoan Technology SNE330 / BTYQ-SNE330 portable gas detector is built around a core philosophy of precision, lightweight design, and reliability. It employs natural diffusion or an external pump-drawn sampling method to detect toxic and combustible gas concentrations in the environment via a non-contact approach, giving early warning of leaks and mitigating personal safety risks.
Modular by Design. The single-gas configuration features swappable, plug-and-play sensor modules, allowing users to flexibly switch between electrochemical, infrared absorption, photoionization (PID), and catalytic bead sensors to match the target gas.
Information at a Glance. A high-definition display provides real-time readings of gas concentration, alarm thresholds, and device status, while onboard storage of 100,000+ data points supports robust traceability and compliance reporting.
Triple-Redundancy Alarms. A 90 dB audible alarm, high-visibility visual indicator, and vibration alert ensure warnings cut through even the noisiest industrial environments.
Built for the Field. Powered by a rechargeable lithium battery for 8+ hours of continuous operation, the lightweight unit features a rugged, corrosion-resistant, and abrasion-proof rubberized housing. Designed for true one-handed operation, it can be comfortably held or clipped directly onto workwear — making it the ideal baseline tool for pinpoint gas monitoring during routine inspections in industrial settings.
2、Multi-Gas Portable Detectors: One Unit, Complete Protection
When industrial environments grow more complex and unpredictable, Nuoan Technology ‘s five-gas and six-gas portable detectors are the clear choice. The SNE360 / BTYQ-SNE360 and SNE380 / BTYQ-SNE380 multi-gas portable detectors simultaneously monitor anywhere from one to six gases, with flexible digital sensor configurations spanning catalytic bead, infrared (NDIR), photoionization (PID), and electrochemical technologies. Users can tailor their detection suite to site-specific demands, covering combustible gases, oxygen, hydrogen sulfide, carbon monoxide, VOCs (volatile organic compounds), and beyond.
The SNE360 series supports both diffusion and external pump-drawn sampling. The SNE380 series, meanwhile, integrates a built-in pump for accelerated response times. Equipped with extended sampling tubes and integrated lighting, the pump-driven configuration lets operators probe deep into confined spaces, pipeline trenches, and well bottoms — bringing reliable detection to the most challenging environments.
Nuoan Technology multi-gas portable detectors feature a crisp high-definition display presenting date, time, gas concentration, and alarm and fault status with complete clarity. Triple-redundancy alarms — a 360-degree LED light ring, a 90 dB audible siren, and vibration — ensure no warning is ever missed, even in the most demanding industrial environments.
Built to an IP66 ingress-protection rating, the ruggedized housing withstands heavy rain, dust infiltration, and hard impacts. An integrated drop-detection system triggers an immediate audible and visual alert if the device takes a fall.
A high-capacity rechargeable lithium battery delivers 10+ hours of continuous runtime in normal operating mode, easily covering full-shift inspection rounds. On-site zero-point correction can be performed quickly in ambient air, while an onboard intelligent compensation algorithm enables continuous, adaptive environmental calibration.
3、Certified to the Highest Standards, Quality Assured
Nuoan Technology ‘s entire portable gas detector portfolio has successfully secured all requisite national certifications, including the National Explosion-Proof Certificate (CNEx), China Compulsory Certification (CCC), Pattern Approval for Measuring Instruments (CPA), and Electromagnetic Compatibility (EMC) certification.
The company is also fully certified under ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and ISO 45001 (Occupational Health & Safety) management systems.
Leveraging more than two decades of accumulated gas sensing expertise and a mature, intelligent manufacturing base, Nuoan Technology delivers large-scale production with unwavering quality consistency and dependable delivery schedules — ensuring every unit that reaches the field meets the same exacting standard.
From precision monitoring to comprehensive protection, Nuoan Technology delivers portable gas detection solutions for every scenario — safeguarding industrial operations at every turn.
