This portable multi gas detector with pump is the latest device developed by our company which features a 2.8-inch TFT color screen display, capable of simultaneously detecting up to six gases. It has an elegant and generous operation interface and supports both Chinese and English display. When the concentration exceeds the preset value, the instrument will issue audible, visual and vibration alarms. The instrument is equipped with real-time data storage function and a USB communication interface, which can be connected to a computer to read set parameters, export records, etc.
The pump suction multi gas detector is a portable safety monitoring device that actively samples through an internal air pump and integrates multiple gas sensors, capable of simultaneously detecting the concentrations of different harmful gases in the environment. Its core value lies in active sampling and multi-functional integration, which can effectively cope with complex and dangerous detection environments.
1.The features of the pump suction combined gas detector are as follows
(1).Active sampling and rapid response: The built-in air pump actively draws air, and the gas can be directly sent to the sensor, greatly reducing the response time for detection and alarm. It is especially suitable for scenarios that require quick results.
(2).Long-distance detection, ensuring safety: By pairing with sampling tubes (up to 10-20 meters in length), operators can sample the gas inside confined Spaces (such as storage tanks and pits) in a safe area, avoiding direct exposure of personnel to dangerous environments.
(3).Multi-gas detection and comprehensive analysis: It can be equipped with 1 to 6 or even more sensors simultaneously to detect multiple gases including oxygen (O₂), combustible gas (LEL), carbon monoxide (CO), hydrogen sulfide (H₂S), and volatile organic compounds (VOCs) at one time.
(4).High protection: The overall protection level of the machine is mostly IP66, and it has the ability to resist water and dust.
(5).Explosion-proof certification: The key components adopt intrinsically safe circuit design and generally pass explosion-proof certifications such as Ex ib IIC T4 Gb, which can be safely used in hazardous areas.
2.Common detection combinations and applications of pump suction multi Gas detectors
(1).The standard configuration of confined space or enclosed space four-in-one (usually O₂, LEL, CO, H₂S) storage tanks, pits, sewers and other environments where personnel may be deprived of oxygen or exposed to toxic gases.
(2).On the basis of the above, the petroleum, chemical and metallurgical industries have added VOC (PID), SO₂, NH₃ pipeline leakage detection, daily safety inspection and equipment maintenance.
(3).Rapid assessment of gas components in fire scenes and areas of unknown chemical leakage: O₂, LEL, CO, H₂S, VOC.
