How to choose a suitable portable gas detector?

2025-03-27

 

In modern industry, fire protection, environmental protection and other fields, the hazards of gas are increasingly valued by people. In order to ensure the life safety of workers and the health of the environment, portable gas detectors have become an indispensable tool.

 

Classification of common portable gas detectors

 

Portable gas detectors are important tools to ensure operational safety. Their technical characteristics and application scenarios vary depending on the type of equipment. According to the type of gas detected, they can be divided into single gas detectors, dual gas detectors, multi-gas detectors, etc. According to the gas sampling method, they can be divided into diffusion gas detectors and pump suction gas detectors.

 

Different types of detectors have their own advantages in technical characteristics and application scenarios. How should we choose?

 

Portable single/dual gas detection

 

Single/dual gas diffusion detectors can detect specific gases with high sensitivity, such as carbon monoxide (CO), hydrogen sulfide (H2S), oxygen (O2), chlorine dioxide (ClO2), sulfur dioxide (SO2), etc.

 

  1. Technical features

 

  • Single detection range Single gas detector only responds to the target gas, suitable for safety monitoring in specific scenarios; dual gas detector can detect two common gases at the same time, such as CO and H2S.

 

  • Simple design and light equipment, easy for individuals to carry. Most are maintenance-free design, low cost of use.

 

  • High sensitivity Electrochemical sensor has a short response time, suitable for rapid detection of gas concentration changes.

 

  1. Applicable scenarios

 

  • Personal protection

 

Operators wear it when entering a potentially dangerous environment, such as oxygen monitoring in a boiler room, or H2S leak detection in a sewage treatment plant.

 

  • Fixed risk area monitoring

 

Used for long-term monitoring of specific gases in high-risk areas, such as places where only specific gases such as CO or O2 need to be detected.

 

  1. Chicheng Electric Instrument Recommendation

 

Chicheng Electric GC260 portable gas detector, small size, easy to carry, can be placed in a pocket or held in the hand. The shell is made of high-strength engineering materials and composite elastic rubber double-color materials, with high strength, good feel, and waterproof, dustproof and explosion-proof.

GC260-2

It is suitable for explosion-proof, toxic gas leakage rescue, underground pipelines or mines and other places, which can effectively ensure the safety of workers and production equipment.

 

Portable all-in-one gas detector

 

The all-in-one gas detector is a detection instrument that can detect multiple (4 or more) different gases at the same time. It detects the presence and concentration of target gas through built-in electrochemical, infrared, catalytic, PID and other types of gas sensors.

 

  1. Technical features

 

  • Sensor combination

 

Supports electrochemical and catalytic combustion sensors, and can expand gas types to meet different needs.

 

  • Real-time monitoring

 

Synchronously detect the concentration of multiple gases under the condition of stable ambient airflow.

 

  • High protection design

 

Most devices are IP67 certified and can operate in harsh industrial environments.

 

  1. Applicable scenarios

 

  • Industrial inspection

 

Gas monitoring in equipment areas of refineries, chemical plants, and steel plants. Enter confined spaces such as storage tanks and pipelines to detect environmental gas concentrations in real time.
