Infrared CO2 analyzer

I. Product Overview

The infrared CO2 analyzer is a high-precision instrument used to detect toxic and hazardous substances in the air of public places. It uses the non-diffusion infrared principle to measure the concentration of carbon dioxide in the air. It features high accuracy, long service life, and minimal cross-interference, making it an essential instrument for environmental and occupational health monitoring.

II. Scope of Application

This instrument is widely used in environmental protection, environmental monitoring, health supervision, occupational health, disease control, and research institutes.

III. Standards

JJG635-2011 "Infrared Gas Analyzer for Carbon Monoxide and Carbon Dioxide"

GB/T18204.2-2014 "Public Place Hygiene Inspection Methods - Part 2: Chemical Pollutants"

GBZ/T 300.37-2017 "Determination of Toxic Substances in the Air of Public Places - Part 37: Carbon Monoxide and Carbon Dioxide"

IV. Technical Features 

1. Android operating system and 7-inch touchscreen display for enhanced real-time human-computer interaction.

2. Large storage capacity, capable of storing over 100,000 data records. 3. Built-in thermal printer prints current data upon test completion.

4. Built-in Wi-Fi allows data upload to the platform for convenient data monitoring (4G module optional).

5. USB data port allows data to be transferred to a USB flash drive.

6. Digital flow sensor displays real-time flow data.

7. High-precision infrared sensor for high measurement accuracy, fast response, and short warm-up time.

8. Supports nitrogen and catalytic zero calibration.

9. Internal constant temperature heating, suitable for outdoor operation in low-temperature environments.

10. Built-in channel switching solenoid valve automatically switches between zeroing and measurement.

11. Temperature and humidity measurement functions and a built-in temperature and humidity compensation algorithm eliminate the effects of temperature changes on measurement data.

12. Displays 0.5-hour, 8-hour, and daily average values, and features timed storage.
