NDIR is hot. Electrochemical is not.
In the comparisons between NDIR and electrochemical sensing technologies, the distinction is becoming clear: electrochemical sensors is becoming a legacy technology in applications where NDIR is available.
One of the main advantages of NDIR is that it relies on optical measurement rather than a consumable chemical reaction. Electrochemical sensors depend on reactive materials that gradually degrade as they operate, which can shorten sensor lifespan and require more frequent replacement or calibration. NDIR sensors, by contrast, measure gas concentration using infrared light, avoiding the chemical wear.
NDIR also offers stronger selectivity in many applications. Electrochemical sensors can be more vulnerable to cross-sensitivity, where gases other than the intended target influence the reading. NDIR sensors can better identify gases based on their unique infrared absorption characteristics.
Have we missed anything? Team NDIR, or electrochemical? Where NDIR is a viable option, do electrochemical sensors still offer distinct value, or are they destined to lose relevance?
