1. Brief introduction：
The gas detector pump suction type four-in-one gas detector consists of a gas sensor module, a microprocessor, and a visual and audible alarm module. The gas sensor adopts smart gas sensors to detect the concentration of explosive gases, hazardous and harmful gases, oxygen, and carbon dioxide in the air. The microprocessor processes the detected signal and displays the concentration values of different gases on the LCD screen in real-time. When the gas concentration exceeds the preset alarm level, the visual and audible alarm module will sound an alarm to remind the worker.
The instrument is equipped with a large-capacity lithium battery as the power supply, which can use continuously for a long time. It is equipped with a built-in sampling pump, which can directly suck in gas samples from the detection site, and is equipped with a dustproof and waterproof design, which can adapt to various harsh environments. This portable gas detector pump suction type is used in confined space and nnderground Operations. It can detect and measure four different gases simultaneously, including oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), and combustible gases (LEL) that displays real-time gas concentrations. The detector also emits audible and visual alarms when gas levels exceed preset levels, ensuring the safety of the worker.
The instrument is easy to operate, with simple control buttons for adjusting settings and accessing data. It is powered by a rechargeable lithium-ion battery, providing up to 12 hours of continuous operation on a single charge. The rugged construction and compact design of the detector make it ideal for outdoor and industrial environments, and it comes with a convenient carrying case for easy transport and storage.

4. Application：
The pump suction type four-in-one gas detector is suitable for the detection of flammable gases, toxic gases, oxygen, and carbon dioxide in various fields such as gas, petroleum, chemical industry, metallurgy, electric power, environmental protection, and firefighting. It is widely used in the detection of gas leakage, gas production, transportation, storage, and other aspects.
5. Calibration:
The gas detector pump type needs to be calibrated once a year to ensure accurate detection. The detector calibration requires the use of a calibration gas and a calibration cap. The calibration gas contains a known concentration of the target gas, which is used to calibrate the instrument to ensure its accuracy. The gas detector should also be regularly inspected and maintained to ensure its normal operation.
