The WE-T233 ammonia gas concentration monitoring transmitter offers multiple transmission methods: LoRa, 4G, NB-IOT, and RS485, with power supply options covering battery power and DC24V power. This transmitter uses highly stable digital sensors to ensure precise real-time monitoring and scientific calculation of ammonia gas concentration values on site. Through communication technologies such as LoRa, 4G, NB, and RS485, long-distance data transmission is achieved. By integrating Shidian Technology’s industrial edge computing gateway products, data was smoothly uploaded to the Shidian Technology equipment management platform, ensuring real-time collection, precise analysis and calculation, secure storage, and intuitive display of on-site ammonia gas concentration values, providing solid technical support and data assurance for related work.
The transmitter body and probe are designed separately, making it suitable for monitoring air quality in residential community garbage stations, waste incineration stations, public toilets, sewers, and other residential and industrial environments. It meets the requirements for online ammonia gas concentration measurement in most industrial applications.
