The manifestation of advanced chemicals sensor technology for the production of cost-effective, miniaturised and lightweight chemical detector, capable of continuous and static measurements in the remote environment, is a latent growth factor in the APAC chemical sensors market.
On the other hand, the growth of chemical sensors market in APAC region is facing challenges that are derived from the resulting output of the use of chemical sensors. The three most crucial restraints of chemical sensors market include,
Chemical sensors are selective in nature. For example, biochemical sensors can be applied only in biochemical process, and their use in other processes can deliver inefficient output.
Upon continuous exposure to haphazard materials and chemicals, the sensitivity of the sensors will degrade. This will result in the persisting replacement of chemical sensors, and create a despise environment for the end-users.
The design of any chemical sensor makes it unidirectional. However, the reversible chemical reactions occurring in an industrial process may alter the monitoring function and thereby, regard the chemical sensors as useless.
