Type of Detection Technology: 

  • Infrared (IR) Sensors: Gao Tek’s IR sensors are highly accurate and specific to CO2. They work by measuring the absorption of infrared light by CO2 molecules. They are suitable for environments with potential interference from other gases. 
  • Chemical/Metal Oxide Sensors: These sensors are cost-effective but may be prone to false alarms. They operate by detecting changes in electrical conductivity when CO2 reacts with a metal oxide. 

Detection Range: Consider the specific application and the expected concentration range of CO2 in your environment. Different detectors may have varying detection limits, so choose one of ours that aligns with your needs. 

Accuracy and Precision: Check the accuracy and precision specifications of the detector. High-precision instruments are essential for critical applications, such as in laboratories or industrial settings. 

Response Time: The response time of a CO2 gas detector is crucial, especially in situations where rapid detection is necessary for safety. Choose our detector with a fast response time to ensure timely warnings. 

Calibration and Maintenance: Regular calibration is necessary to maintain the accuracy of the detector. Consider the ease of calibration and whether the device has self-calibration features. Additionally, check the maintenance requirements and choose a detector that suits your operational capabilities. 

Environmental Conditions: Consider the environmental conditions where the detector will be used. Our detectors are better suited for extreme temperatures, high humidity, or corrosive environments. Ensure that the chosen detector can operate reliably in your specific conditions. 

Power Source: Determine whether the detector requires a power source (battery or electrical) and choose one that aligns with the available infrastructure in your environment. Some of Gao Tek’s detectors may offer options for both battery and external power. 

Display and Alarm Features: Look for detectors with clear and easily readable displays. Consider whether the device provides real-time measurements and alarms. Audible and visual alarms are important for alerting occupants in the event of elevated CO2 levels. 

Data Logging and Connectivity: Some detectors offer data logging capabilities, allowing you to track CO2 levels over time. Connectivity options like USB or wireless interfaces may also be useful for data retrieval and analysis which our detectors provide. 

Certifications and Compliance: Ensure that the CO2 gas detector meets relevant safety standards and certifications. Gao Tek’s detector’s compliance with regulations such as UL (Underwriters Laboratories) or EN (European Norm) standards is essential for safety and reliability. 

Cost Considerations: Compare the costs of different detectors, but keep in mind that prioritizing safety and reliability is crucial. Cheaper options may compromise accuracy and features.Â
