Description
The DL-302 is a data logger module designed to accurately measure CO2, temperature and humidity.
It contains RS-485, Ethernet and PoE communication interfaces together with a 2.8" LCD Touch Screen display that can be used to display a variety of CO2, temperature, humidity and dew point data. The data storage memory can store up to 600,000 CO2, temperature, humidity and dew point records. The Data Logger Utility is included to allow retrieval and display of data in a powerful chart format that can be exported to Excel.
Configuration is done via the Touch Screen or Web Server. An Android App is also available to display the current values from devices connected on a local network.
Can be used as part of an environmental monitoring / data acquisition solution using Modbus Protocol and compatible packages. Please contact us to discuss any requirements of this nature.
