  • Page 5: Introduction

    1. Introduction The DL-300 series is a data logger designed to accurately measure and record the concentration of carbon monoxide/carbon dioxide in the atmosphere, temperature and humidity. It can display the real-time data and log the concentration of CO, CO temperature and humidity with a date and time stamp for downloading later.
  • Page 6 Characteristics Simultaneous display for CO/CO level, temperature, humidity and dew point CO measurement range: 0 ~ 1000 ppm measurement range: 0 ~ 9999 ppm Non­dispersive Infrared (NDIR) sensor with Automatic Baseline Correction algorithm for CO measurement Able to store up to 450,000 records 2.8"...
  • Page 7 Features NDIR Sensor NDIR (Non-Dispersion Infrared) is based on one of the natural properties of CO molecules: CO molecules absorb light at a specific wavelength of 4.26 µm. This wavelength is in the infrared (IR) range. High concentrations of CO molecules absorb more light than low concentrations.
  • Page 8 Data Logging Software The DL300 Utility can be used to configure the modules, monitor real-time data and show the run chart, log alarm events, group DL-300 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.

  • Page 17: Cabling For Power And Network

    2.4 Cabling for Power and Network Note Do not install the DL-300 module near a vent, a ventilation fan or a door where the air flows faster. Also avoid putting the module on a desktop below the nose and mouth to prevent incorrect measurement. Avoid installing in locations where the temperature is below 0°C or above 50°C.
  • Page 18 The iAir App and DL-300 Utility search the logger by broadcast, therefore only the devices on the same subnet can be searched out. It means that the host PC, Android devices and the logger must have the same broadcast address. The broadcast address for an IPv4 device can be obtained by performing a bitwise OR operation between the bit complement of the subnet mask and the IP address for a device.

  • Page 72: Faq

    8. FAQ Q1: What is ABC (Automatic Baseline Correction)? A: ABC stands for the Automatic Baseline Correction which is used to adjust a shifted baseline to the carbon dioxide level in fresh air. In case of normal indoor application, the carbon dioxide level drops to nearly outside air where there are no human, green plants or anything to elevate the carbon dioxide levels on weekday evenings or weekends, the ABC algorithm constantly keeps track of the lowest reading and slowly corrects it as the expected value in fresh air typically around 400 ppm.
