Handheld combustible gas leak detector can detect extremely low concentrations of combustible gases
Date: 2025-10-19Read: 0
In modern industrial production and daily life, the safety of gas leaks has always been a focus of attention, especially for combustible gases. Combustible gas leakage may lead to catastrophic accidents such as fires and explosions, therefore, timely detection and prevention of combustible gas leakage are important measures to ensure safety. As an important safety detection tool, handheld combustible gas leak detectors have been widely used in multiple industries.
Handheld combustible gas leak detectorWorking principle:
1. Catalytic combustion sensor:
Catalytic combustion sensors determine the concentration of gas by detecting the change in heat generated by the combustion of gas on the sensor surface. Its advantages are fast reaction speed and the ability to accurately detect most combustible gases, such as methane, propane, etc.
2. Electrochemical sensors:
Electrochemical sensors use the changes in current generated when gases react with electrochemical reagents to determine gas concentration. It is suitable for detecting certain specific gases, such as ammonia, carbon monoxide, etc.
3. Infrared sensor:
Infrared sensors determine the concentration of gases by measuring their absorption of infrared light. Its characteristic is strong selectivity towards multiple gases and fast response speed.
The main functions of the handheld combustible gas leak detector are:
1. High sensitivity:
The sensor has high sensitivity and can detect extremely low concentrations of flammable gases, helping users detect leakage hazards early.
2. Alarm function:
When the detected concentration of combustible gas exceeds the safety threshold, the detector will sound, light, or vibrate an alarm to remind staff to take emergency measures to avoid accidents.
3. Data recording and storage:
Some have data recording and storage functions, which can store detection data in internal memory for easy subsequent analysis and traceability.
4. Multiple gas detection:
The advanced handheld detector can simultaneously detect multiple gases and is suitable for different working environments.
5. Gas concentration display and real-time monitoring:
The detector is equipped with a display screen, which can display the current gas concentration in real time, making it convenient for staff to observe and analyze.
6. Easy to carry and use:
As a handheld device, the detector is compact in size, lightweight, easy to carry and operate, and suitable for on-site use.
