【Case Background】A large new material manufacturer specializes in high-performance carbon fiber production. High-purity nitrogen serves as shielding gas during critical carbonization and graphitization processes to isolate oxygen and prevent material oxidation that degrades product performance. The enterprise originally operated a PSA nitrogen generator yet lacked precise nitrogen-oxygen analysis equipment, resulting in unstable nitrogen purity, fluctuating product qualification rates and persistently high production costs. To resolve this bottleneck, the company adopted Chengdu HonryTech HT-LA260 nitrogen-oxygen analyzer to integrate with its existing PSA nitrogen generation unit.

 【Application Process】Equipped with an advanced imported long-life zirconia oxide detector, the HT-LA260 nitrogen concentration analyzer delivers ultra-high sensitivity and rapid response. When integrated with the PSA nitrogen generator, it performs real-time, accurate measurement of oxygen concentration in output nitrogen, with measuring ranges of 10/100/1000 ppm to 21.000% O₂/N₂ and measurement accuracy of ±2% F.S. Upon abnormal oxygen fluctuations, the analyzer instantly transmits data to the nitrogen generator’s control system, which automatically adjusts adsorption duration, pressure and other parameters to sustain nitrogen purity consistent with production standards.

During field operation, the HT-LA260 demonstrates robust data processing capacity, generating detailed historical oxygen concentration reports. By analyzing these datasets, plant technicians accurately identify operating patterns and performance degradation trends of the nitrogen generator to predict potential faults in advance. For instance, historical oxygen data revealed gradual attenuation of molecular sieve adsorption performance, enabling scheduled maintenance and replacement to prevent production shutdown and product quality failures caused by ineffective molecular sieves.

【Customer Feedback】Mr. Wang, Production Supervisor of the enterprise, commented positively: “After deploying Chengdu HonryTech HT-LA260 nitrogen-oxygen analyzer, our production performance has improved dramatically. Previously unstable nitrogen purity dragged our product qualification rate below 80% at times. Thanks to precise monitoring by the analyzer and automatic parameter adjustment of the nitrogen generator, our qualification rate remains steadily above 95%. We have cut substantial raw material and rework costs, generating an estimated additional millions of RMB in annual profits.”

Mr. Zhang, Equipment Maintenance Engineer, praised the analyzer highly: “This analyzer features user-friendly operation and an intuitive display screen; our operators master proficient use after brief training. It maintains outstanding stability with nearly zero breakdowns since commissioning, and simplified daily maintenance drastically reduces our workload. Most importantly, historical data reports greatly support equipment maintenance and performance optimization, shifting our maintenance mode from reactive repair to proactive upkeep, significantly boosting equipment operating efficiency and service life.”

Ms. Li, Head of the Procurement Department, shared her evalsuation from a cost perspective: “We selected the HT-LA260 nitrogen concentration analyzer primarily for its cost-performance ratio, and our decision has proven fully justified. Apart from its reasonable pricing, the economic benefits it delivers far exceed the initial equipment investment. Our production runs more stably, product quality is reliably guaranteed, and our market competitiveness has strengthened. We will prioritize this brand for all future equipment renewal projects.”
