Using MCU chip to achieve low power consumption operation, detection error ≤ +/- 3% F. S, Response Time ≤ 30 seconds, support 4-20mA and RS485 and other signal output, can be operated by remote control without opening the lid, with local sound and light alarm function.
Using infrared NDIR detection principle, range 0-8% Vol, Response Time ≤ 30S, support 4-20mA, RS485 and switch output, Modular design is convenient for System integration and maintenance.
