The 900 series pump-suction portable gas detector is a detection device that can continuously monitor gas. It is equipped with a small gas pump, and the power supply drives the gas pump to extract gas samples from the gas in the test area. Then the sample gas is sent to the instrument for detection.
The portable gas detector is equipped with a 1800mA capacity battery, which is light and easy to carry. It can detect the composition and concentration of various gases in the environment. Accurately capture the slight changes in gas concentration, so as to timely discover potential safety hazards.

Pump-suction Type vs. Diffusion Type
The diffusion type gas detector is a gas in the detection area that flows slowly into the instrument with the free flow of air for detection. This method is affected by the detection environment, such as ambient temperature, wind speed, etc. The characteristic of the diffusion type gas detector is low cost.
The characteristics of the pump-suction type detector are fast detection speed, long-distance measurement of dangerous areas, and safety of maintenance personnel. Others are the same as the diffusion type gas detector. The sample gas is detected by the sensor of the instrument and then amplified and sorted by the circuit to convert it into the corresponding value displayed on the screen.


Gas Concentration and Leak Detection
Featured Applications
Fixed Gas Detector with Remote Sensor is mainly used in environments where data needs to be viewed outdoors for confined space detection. It also has on-site data display function, explosion-proof sound and light alarm function, detection concentration signal conversion and transmission function, relay output control and other functions.
Suitable for use in incubators, confined spaces, and non-contact gas monitoring environments. The sampling method can be set to a pump suction type by adding an air pump, and changes can be made according to the actual requirements of the site.
- Industrial field: widely used in petroleum and petrochemical, chemical plants, smelters, steel plants, coal plants, thermal power plants and other industries. Used to monitor the oxygen concentration in the production process. Prevent safety accidents such as explosions and fires.
- Medical field: In the intensive care unit, operating room, ambulance and other places of the hospital, it is used to monitor the oxygen supply of patients to ensure the safety of patients.
- Scientific research field: In scientific research laboratories, it is used for gas composition analysis and control in various experimental processes to ensure the accuracy and reliability of experimental results.
- Other fields: It can also be used in environmental monitoring, school scientific research, building construction, fire alarm, sewage treatment, garbage treatment plants, tunnel construction, oil pipelines, gas stations and other places. Ensure personnel safety and normal operation of equipment.
