Wireless H2S Sensor
The R718PA4 is a wireless communication device that detects H2S content in ambient air. R718PA4 detectable air H2S concentration levels. The main unit and H2S sensor are connected with the RS485 interface and the detected data to the other equipment is shown via a wireless network that employs compliance Lora (TM) wireless communication protocol standards.
