  • Able to record CO, CO2, HCHO, TVOC, Temperature, Humidity and Dew Point Measurements
  • Non-dispersive Infrared (NDIR) CO2 Sensor
  • HCHO: Electrochemical Sensor
  • VCO: Metal-Oxide Sensor
  • Up to 450,000 records with date and time stamps
  • Supports the DCON, Modubs 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 HCHO, TVOC, CO, CO2, 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.
