•AM4205 series designed and tested to meet UL 60335-2-40 standard with 5V input, UART & Analog Output
•Based on mature AM4205 series, the AM4203 series has incorporated outputs to extend with RS485, Relay Outputs, 12V/24VDC power supply and Modbus communication protocol. It provides more efficiently integration with customer controlling systems
| Key Features | NDIR | Metal-Oxide-Semiconductor | Thermal Conductivity | Comparison |
| Selectivity | Excellent | Poor | Fair | NDIR with excellent selectivity MOS easily poison and impact by interference gas |
| Accuracy | Excellent | Fair | Fair | NDIR Matrix calibration to ensure accuracy MOS and TC sensitive to temperature and humidity change |
| Response | Excellent | Fair | Poor | NDIR Fast response MOS slow recovery rate, need long time preheat |
| Temperature and Humidity Impact | No Impact | Accuracy Easily Influenced | Accuracy Easily Influenced | TC easily impacted by temperature and humidity |
| Life time | Excellent | Poor | Fair | NDIR long-term stability, no false alarm MOS short life time, possible for false alarm TC has relatively longer life time than MOS, but still shorter with NDIR |
| UL60335 compliance | Fully Compliant | Not Fully Compliant | Not Fully Compliant | Cubic NDIR sensor could fully comply with UL60335 & EN60079 Neither MOS or TC is comply with UL60335-2-40 Annex LL |
