| Accuracy | 1.0～10,000 ppm: ±10% of reading or ±1.0 ppm (whichever is greater). This accuracy is based on a single-point calibration using methane at 100～500 ppm (including drift) at calibration temperature and humidity.3,000～50,000 ppm: ±10% of reading, using 20,000 ppm methane single-point calibration. |
| Repeatability | ±2% at 500ppm methane |
| Dynamic Range | 1.0～50,000 ppm methane |
| Linear Range | 1.0～50,000 ppm methane |
| Minimum Detection Limit | Defined as 7 times the standard deviation of peak-to-peak noise: 0.5ppm methane |
| Response Time (T90) | Using 10,000ppm methane, 20℃: ≤2.5 seconds |
