AM4205H-LC R32 A2L Refrigerant Leak Detection Sensor

Description

The AM4205H-LC Cubic Refrigerant Gas Sensor series can detects refrigerant gases for safety or alarms. Using industry standard UART, in seconds the sensor begins reporting 0-50% LFL (Lower Flammability Limit, equal to LEL Lower Explosive Limit) in with high accuracy. This enhanced version also includes Modbus output.
