The CL-220 series of data logger devices can be used to record PM1/PM2.5/PM10 and the number of particles (0.3μm, 0.5μm, 1μm, 2.5μm, 5μm, 10μm), CO, CO2, NH3 , H2S, HCHO, TVOC, 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 iOS 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 machine-to-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

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 iAir 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.

Simple and Powerful iAir Utility 

The iAir Utility is a powerful tool that is designed for configuring the modules, monitoring real-time data, grouping CL-200 modules to view and manage the status of distribution groups, downloading log data, which can be exported to a CSV fi le that can then be imported into any industry-standard software or spreadsheet for analysis.
