Product Introduction

The L series wireless transmission fixed ethylene oxide detector is a new product developed in the past two years to adapt to the market, named after its use of wireless signal transmission. Mainly detecting the gas concentration in the on-site environment, and using wireless communication (WIFI/ZIGBEE/LORA/433M/GPRS) to transmit the detected ethylene oxide gas concentration signal to the corresponding wireless signal receiving device. The wireless receiving device sends the received signal to the control host or PC terminal, PLC control system, DCS system, etc. for unified display, management, and control. Compared with traditional detectors, it saves a lot of expenses such as wiring installation, labor costs, and maintenance, greatly reducing engineering costs.
