  • Able to record H2S, Temperature, Humidity and Dew Point Measurements 
  • Up to 450,000 records with date and time stamps 
  • Supports the DCON, Modbus RTU/TCP, and MQTT Protocols 
  • Includes RS-485/Ethernet Communication Interfaces 
  • Relay Output for Alarm or IAQ Device Control 


The CL-200 series of data logger devices can be used to record CO, CO2, HCHO, TVOC, NH3, H2S, temperature, humidity and dew point information, including the date and time stamps, and are able to store up to 450,000 downloadable records.

Real-time data can be accessed from the CL-200 data logger from anywhere and at any time using the free Windows software, the iSO App, or the Android App, as long as they are connected to the same local network as the data logger.

Support is provided for common industrial protocols such as DCON, Modbus RTU, and Modbus TCP, as well as the emerging machineto-machine (M2M)/)IoT (Internet of Things) connectivity protocol – MQTT. The CL-200 data logger can be connected via widely used communication interfaces including RS-485, Ethernet and PoE, meaning that the device can be easily integrated into existing HMI or SCADA systems, ensuring trouble-free maintenance in distributed control systems.

Supports the MQTT Protocol for IoT Applications

Data Logger Application

Multi-platform Remote Access Software

Real-time data from the CL-200 data logger can be accessed from anywhere and at any time using the DL300 Utility, the iOS or Android App, or via a regular web browser, as long as they are connected to the same local network as the data logger.

Data Logger Application

Simple and Powerful CL-200-E Utility

The DL300 Utility can be used to configure the modules, monitor real-time data, group CL-200-E modules so that the status of distribution groups can be viewed and managed. The utility also allows the log data to be downloaded and exported to a .CSV file that can then be imported into any industry-standard software or spread sheet for analysis.
