1.Brief introduction
The portable multi gas detector with pump is capable of simultaneously detecting up to six gases. When the concentration exceeds the preset value, the instrument will issue audible, visual and vibration alarms.
The pump suction gas detector is equipped with a 2.8-inch color TFT high-definition LCD screen, supporting both Chinese and English interfaces and switching between multiple concentration units (ppm, mg/m³, %VOL, %LEL, etc.). It is equipped with a large-capacity lithium battery of 4500mAh, ensuring a battery life of over 10 hours. The instrument can store 490,000 real-time data entries. In addition, the detector supports exporting data to a computer via USB. Optional features include interconnection and interoperability, 4G upload, GPS and other functions.
This multi gas detector is equipped with a high-performance micro suction pump that can actively draw gas into the detection chamber at a stable flow rate of 500-800 mL/min. Through reactions with various sensor arrays such as electrochemical, catalytic combustion, and PID photoionization, the gas is converted into electrical signals for analysis. This active sampling method does not rely on the natural diffusion of gas, so it can directly draw gas samples from hard-to-reach areas such as deep parts of pipelines and corners of confined Spaces. Its response speed and detection accuracy far exceed those of traditional diffusion device.
2.Features
(1).Core design: Different from the passive waiting gas diffusion type, it can achieve long distance (>10 meters) sampling and rapid response through the active suction of the built-in micro air pump.
(2).High performance: One device for multiple measurements can be flexibly configured with 6 types of sensors. Multiple protection explosion-proof certifications Ex ib IIC T4 Gb, high protection grade IP66, with the ability to resist electromagnetic interference and overload shock.
(2).Durable design: The shell is made of high-strength engineering plastic, which is shockproof and drop-resistant. It is equipped with a standard water trap filter, which can filter out dust and water vapor to extend the service life of the sensor.

4.Application
Before entering confined Spaces such as sewage Wells, storage tanks, underground pipelines, ship holds, and mines, it is mandatory to use a pump suction detector for detection first, then entry as per regulations. The advantage of the pump suction design lies in its ability to sample separately from the upper, middle and lower parts of the confined space, grasp the gas distribution in the vertical direction, and avoid the detection blind spots caused by gas stratification in traditional detectors.
In petrochemical and mining production, portable multi gas detector with pump is standard safety instrument in storage tank areas, along pipelines and in production workshops. In the natural gas storage tank area, long tube probes of pump suction equipment are used to reach deep into the bottom of the tank for trace leakage detection. During mine inspection, the pump suction alarm can be installed on the mine inspection robot to conduct directional detection of the accumulated gas at the top of the tunnel.
5.Maintenance
(1).Core component maintenance: Regularly check the pump suction force. Block the air inlet with your finger for 5 seconds to feel the suction force. The air intake filter needs to be cleaned more in a dusty environment. Strictly avoid the impact of high-concentration gases on the sensor to prevent poisoning and failure.
(2).Regular calibration management: Calibration is usually required every 3 to 6 months or no more than one year, using standard gases with a concentration of approximately 50% of the full scale. Strictly follow the sequence of first introducing zero-point gas, such as high-purity nitrogen, and then calibration cylinder gas.
