Type of Gas to be Detected: Identify the specific gases you need to detect. GAO Tek’s combustible gas detectors are designed to detect specific types. Common combustible gases include methane, propane, butane, hydrogen, and others.

Sensor Technology:

  • Catalytic Bead Sensors: Sensors use a heated coil to burn gas, and the heat increase is proportional to the gas concentration.
  • Infrared Sensors: Sensors detect gas by analysing the absorption of infrared light. They are often more selective and less prone to false alarms.
  • Semiconductor Sensors: Sensors measure changes in electrical conductivity when exposed to combustible gases.
  • Sensitivity and Range: Consider the sensitivity of detector and whether it meets the concentration levels you expect to encounter. Also, check the detection range to ensure it covers the potential concentration of gas in the environment.

Response Time: We have response time of gas detector is critical in emergency situations. Faster response times can provide quicker warnings, allowing for faster evacuation or intervention.

False Alarm Rate: A reliable GAO Tek detector should have a low false alarm rate. Look for detectors with advanced features that help reduce false alarms, such as signal filtering and compensation for environmental factors.

Environmental Conditions: Consider the environmental conditions in which GAO Tek’s detector will be used. Some detectors may be better suited for extreme temperatures, high humidity, or corrosive atmospheres.

Power Source: Choose between battery-operated and hardwired GAO Tek detectors based on your needs and the availability of power sources in the installation area.

Display and Alarm Features: Look for detectors with clear and easy-to-read displays. Audible and visual alarms are essential for alerting individuals in the area. Some detectors may also have vibration or remote alarm capabilities.

Maintenance and Calibration: Regular calibration and maintenance are crucial for the proper functioning of GAO Tek’s gas detectors. Consider GAO Tek detectors that are easy to calibrate and have features like self-testing and diagnostic capabilities.

Certifications and Standards: Ensure that GAO Tek’s detector meets relevant safety standards and certifications for the specific industry or application. Common certifications include ATEX, UL, CSA, and others.

Data Logging and Connectivity: Our detectors come with data logging capabilities, allowing you to track gas levels over time. Connectivity options like Bluetooth or wi-fi can be useful for remote monitoring and data retrieval.

Cost and Budget: Consider your budget and compare the features of detectors within that range. Balance the cost with the required performance and features for your specific application.

Installation and Mounting: Determine the ease of installation and the mounting options available for GAO Tek’s detectors. Some detectors are designed for fixed installations, while others are portable for flexible use.
