Infrared carbon dioxide CO2 detector

OC-905 Portable CO2 gas detector

OC‑905 portable CO₂ gas detector is a high‑precision handheld detection device built‑in sampling pump. It accurately measures carbon dioxide concentration on‑site, equipped with clear LCD real‑time data display, sound‑light alarm for over‑threshold value. Compact and lightweight design supports on‑site mobile inspection, widely used for industrial environment safety monitoring.

Description:

OC-905 Portable gas detector designed with the inner pump and the famous brand sensors, with stable performance and high accuracy. Used to detect the single gas concentration for the Combustible gas, Toxic gas, Carbon Dioxide, Oxygen, TVOC, etc. It can directly display the gas concentration data on the screen, the data also could be exported to the computer by USB cable.

For the portable gas detector, it is widely used in petroleum and petrochemical, metallurgy, chemical industry, coking, municipal, biological pharmaceutical, home environmental protection, school laboratory, automobile exhaust, power, ships, sewage treatment and other places that need to detect flammable, explosive, toxic and harmful gases


Function:

Inspect the gas concentration and alarm when it reaches preset alarm level.

High accuracy, good stability and good repeatability, long working life.

One-key operation to restore to factory default setting.

Adjustable two-stage audible-visual alarm threshold value.

Powered by rechargeable lithium battery with big capacity.

The built-in pump, stable flow rate, can be opened or closed;

Feature:

  • Multi Gas Detection: Supports combustible gas, oxygen (O2), carbon dioxide (CO2), toxic gases and TVOC

  • Built-in Pump Sampling: Stable flow rate (300ml/min) for fast and accurate detection

  • High Precision Sensors: Imported sensors with intelligent algorithm and temperature compensation

  • Audible & Visual Alarm: Dual alarm system with ≥75dB buzzer and LED light

  • Data Storage & Export: Stores up to 100,000 records, USB data export supported

  • Explosion-Proof Design: Certified Ex ib IIC T4 Gb for hazardous environments

  • Long Battery Life: Rechargeable lithium battery, up to 12 hours operation
