Product Descriptions

The AW3485M network type temperature and humidity transmitter is a high-performance industrial temperature and humidity transmitter with

battery recording function. It measures the temperature and humidity of the environment and displays it in digital form on the local display

screen. When the measured data exceeds the limit, a control signal is output and an audible alarm signal is generated. At the same time, in

response to the command sent by the host, the measured data is uploaded to the host in the form of a data packet through the RS485 bus, and

the data is recorded according to the set recording cycle. This temperature and humidity transmitter has the characteristics of small size, light

weight, wide range, high accuracy, fast response speed, and good long-term stability, making it widely used in various fields that require

measurement and control of temperature and humidity in the air, such as building automation, climate and HVAC signal acquisition, climate

stations in museums and hotels, warehousing and logistics, medical industry, and computer room temperature monitoring.
