High Development and Manufacturing Costs
The development and manufacturing expenses for NDIR sensors must be considered a significant hurdle that affects cost-sensitive applications. Research and development of sensors requiring high performance and reliability with miniaturization requires major investments. The high manufacturing expenses create a barrier for the non-dispersive infrared market that restricts smaller companies from entering the NDIR sensor market, making these sensors less available to some business sectors.
The production of advanced NDIR sensors with high-performance miniaturization and reliability status remains expensive, which makes them impractical for broad implementation, especially in price-conscious deployment fields. The substantial financial demands associated with NDIR sensor research and development create entry difficulties for smaller businesses that restrict affordability in specific sectors, thus affecting general sensor integration.
Emphasis on sustainability and environmental concern The increasing awareness about environmental issues worldwide makes the non-dispersive infrared market more focused on green practices and sustainability methods. The production industry embraces environmentally friendly technological solutions to reduce sensor-generated environmental hazards. NDIR sensor production receives energy-efficient manufacturing improvement, which leads to reduced environmental impact for these devices during their entire lifecycle.
