Anyone who works with electrochemical gas measurement also knows its weaknesses: sensor drift, regular maintenance and a limited service life can impair operational reliability and cost-effectiveness. Electrochemical sensors quickly reach their limits, especially in long-term stable or low-maintenance applications.
NDIR technology (non-dispersive infrared measurement) offers a powerful and often superior alternative here. It impresses with its high long-term stability, low maintenance requirements and precise measurement results - even in demanding environments.
Micro-Hybrid develops and produces customized IR components and sensor systems for reliable gas analysis based on NDIR. Compare both technologies directly - and find out whether a change of technology can significantly improve your application.
Direct comparison: NDIR vs. electrochemical gas sensor technology
Criterion |
NDIR |
Electrochemical |
|---|---|---|
| Measuring principle | physical (infrared option) | chemical reaction |
| Target gases | CO₂, CH₄, SF₆, hydrocarbons etc. | CO, NOx, O₂, H₂S etc. |
| Long-term stability | Very high (up to 10 years) | limited (1-2 years) |
| Calibration effort | low | high, regularly required |
| Maintenance | minimal | High effort, sensor replacement necessary |
| Environmental influences | Measuring principle | Life cycle costs |
When is it worth switching to NDIR?
These questions will help you decide:
Do you measure gases such as CO₂, CH₄, SF₆?
NDIR sensors are particularly efficient when measuring IR-active gases such as carbon dioxide (CO₂), methane (CH₄) or sulphur hexafluoride (SF₆). These gases absorb infrared light at specific wavelengths - ideal for non-dispersive infrared measurement.
High selectivity without cross-sensitivities
Do you value low-maintenance sensor technology with a long service life?
NDIR sensors require no electrochemical reagents - eliminating the need for regular calibrations, sensor replacement or chemical ageing processes.
Up to 10 years of maintenance-free operation - ideal for installations that are difficult to access
Should operating costs fall permanently?
Less maintenance, fewer spare parts, less calibration work: NDIR sensors significantly reduce your life cycle costs.
Investment in long-term stability pays off - especially with a large number of devices
Do your systems work in industrial environments with temperature fluctuations?
NDIR technology is insensitive to humidity and temperature changes - perfect for harsh environments, industrial halls or outdoor applications.
Stable measurement results even in difficult ambient conditions
Is stable, drift-free long-term use important?
Thanks to the physical measuring principle, NDIR sensors deliver long-term stable results without chemical ageing or drift.
High reliability - especially for safety-critical or automated systems
If you answer ‘yes’ to more than 3 questions, it is worth taking a look at NDIR.
