How do you switch between pump suction and diffusion measurement modes on a four-in-one gas detector?
The pump suction measurement mode relies on the built-in air pump to actively extract gas from the surrounding environment for detection, making it particularly suitable for scenarios that require precise measurement or remote sampling. When the pump suction mode is enabled, the instrument will immediately start the air pump, quickly extract gas through efficient sampling devices such as swan neck sampling probes, and conduct detailed analysis inside the instrument. The significant advantage of this mode is that it can significantly improve the accuracy of detection and the flexibility of operation.
In contrast, the diffusion measurement mode relies on the principle of natural gas diffusion to the detector sensor for measurement. This mode does not require air pump assistance and is particularly suitable for routine environmental monitoring or scenarios that do not require frequent sampling. In diffusion mode, the instrument can continuously monitor the gas concentration in the surrounding environment. Once the concentration exceeds the preset alarm threshold, the alarm system will be immediately triggered.
Switching between pump suction and diffusion measurement modes on a four in one gas detector is usually very simple. Everyone only needs to operate through the menu interface on the instrument. The specific steps are as follows:
1. Enter the main menu of the instrument and find "Measurement Mode" or similar options;
2. Use the up and down keys to select "pump suction mode" or "diffusion mode";
3. Press the confirm button to save and exit the menu.
By following the above method, the instrument will switch to the selected measurement mode and start working.
It is worth noting that before switching measurement modes, users should ensure that the instrument is in a stable state and the surrounding environment meets safety requirements. In addition, according to different application scenarios and detection requirements, users can flexibly choose between pumping or diffusion modes for gas detection.
