Product catalog summary

Introduction
This document introduces a portable carbon dioxide (CO2) gas detector developed by Wuhan Cubic Optoelectronics Co., Ltd. The device integrates Non-Dispersive Infrared (NDIR) technology and is designed for CO2 leakage detection, providing audible and visual alarms when dangerous levels are detected.

Working Principle
The detector operates on the principle that CO2 gas absorbs infrared light at specific wavelengths, following Lambert-Beer's Law. The NDIR sensor uses this principle to measure CO2 concentrations accurately.

Features
The device features high accuracy and resolution, automatic zero calibration, dual-range settings for high CO2 concentrations, and a diffusion-type sampling method. It is equipped with a high-capacity rechargeable lithium battery and provides real-time gas concentration display via LED.

Dimensions: 93mm×62mm×25mm, Weight: 0.15kg

Applications
The portable CO2 detector is suitable for various applications including greenhouses, fruit/vegetable storage, incubators, mushroom farms, brewing, ventilation verification, carbonated drink dispensing, indoor air quality monitoring, and safety in parking areas.

Operational Guidelines
The device allows for setting alarm points with a sound intensity of at least 75dB at 1m distance and optical signal visibility of at least 20m in the dark.

Instrument Configurations
The detector comes with a remote controller and requires an input of AC220V with an output of DC5V.

VvUrtAfX CUIJiC OKTO^kCTKONjCS CO^L.TD. 'Working principle ❖ C02 gas is composed of different types of atoms have absorption spectrum in infrared range. Absorption intensity abides by Lamber-Beer's Law. Basic working principle of NDIR sensor is as below, VvUrtAfX CUIJiC OKTO^kCTKONjCS CO^L.TD. Basic mathematical model: A majority of both organic and inorganic polyatomic gas have specific absorptive wavelength in infrared region. It observes Lambert-Beer Law formula I = I0e-kpl when infrared light is coming through.
