Technology & Products
Key Products
Gas analysis instruments (oxygen analyzers, dew point meters, water content meters, chromatography, THC meters, thermal conductivity analyzers, hydrogen analyzers, H2S analyzers, optical gas analyzers); Environmental monitoring equipment (NOx analyzers, ozone analyzers, high-temperature humidity meters, VOCS chromatography); Industrial solutions (air separation ASU, protective atmosphere furnaces, gas mixers, wave solder ovens, reflow furnaces); Mass flow meters; Water quality analysis instruments; Measurement and analysis equipment for metallurgy, electronics, semiconductors, petrochemicals, power generation, and environmental protection
Technological Advantage
CLAIMED: Precision gas analysis instruments for metal additive manufacturing inert atmosphere control (oxygen/nitrogen monitoring in SLS, LPBF, binder jetting, DED). Prevents oxidation and contamination by maintaining oxygen levels below LOC (limiting oxygen concentration). DEFENSIBLE: Patent portfolio (multiple invention patents + hundreds of utility models) suggests defensibility. VERIFICATION: No independent performance benchmarks, customer testimonials, or accuracy/response-time specifications provided.
Differentiation
Value Proposition
Developer and manufacturer of precision gas analysis instruments—including oxygen analyzers (trace, high-content, portable), thermal mass flow meters, dew point analyzers, thermal conductivity analyzers, and IR/laser gas analyzers—providing inert atmosphere monitoring and control for industrial processes. In additive manufacturing, their oxygen sensors and gas analyzers are used to monitor and control argon/nitrogen environments inside metal 3D printing build chambers (SLS, LPBF, binder jetting, DED), ensuring oxygen levels stay below the limiting oxygen concentration (LOC) of metal powders to prevent oxidation, contamination, and explosion risk. Founded 2004; holds multiple invention patents and hundreds of utility model/design patents; markets products globally.
How They Differentiate
Chang Ai differentiates itself as a world-leading high-tech enterprise in gas analysis and detection, leveraging 20 years of independent R&D and 6 core technologies to offer a comprehensive portfolio of gas analysis instruments and solutions.

Growth & Milestones
Growth Metrics
The company developed China's first maintenance-free coke oven gas system in 2010, which was successfully put into operation at Shandong Laigang. In 2011, their ion current oxygen analyzer became the designated product for the South Pole expedition team. They received the Shanghai Science and Technology SME Technology Innovation Fund in 2012 for their zirconia principle nitrogen oxygen analyzer, and their oxynitride analyzer gained the Shanghai High-Tech Achievement Transformation Project. The company entered the iron, steel, metallurgical, and coal chemical industries in 2011 and became a member of the China Gas Association. They developed a multi-component biogas analyzer for municipal biogas engineering monitoring using independent innovation patented infrared and fuel cell principle sensors, creating an industry pioneer.
