| Principle |
Non dispersive infrared sensor (single beam system)
O2 sensor: built-in magnetic or galvanic sensor, or external zirconia sensor (ZFK7) |
| Ranges |
NO: 0–200 ppm…5000 ppm
SO2: 0–200 ppm…10 vol%
CO2: 0–100 ppm…100 vol%
CO: 0–200 ppm…100 vol%
CH4: 0–500 ppm…100 vol%
Built-in galvanic O2 sensor: 0–10 vol%…25 vol%
Built-in magnetic O2 sensor: 0–5 vol%…100 vol% or 100–95 vol%
External zirconia O2 sensor: 0–5 vol%…25 vol% |
| No. of ranges |
Up to 2 ranges per component |
| Repeatability |
≤ ±0.5% FS |
| Linearity |
≤ ±1% FS |
| Zero drift |

For NO and SO2 of ranges below 500 ppm, auto calibration is necessary before measurement. |
| Span drift |
≤ ±2% FS per week |
| Response time (for 90%) |
10–30 s (depends on ranges) |
