Why use a gas detector with a pump?
A gas detector with a pump allows you to easily inhale air from unknown and potentially toxic or combustible atmospheres into your location. Then, you can view the results of the monitor in an area that you know is safe.
The pump really keeps you from getting hurt.
Once you have evaluated the air sample using a gas detector with a pump and confirmed that it is free of any toxic or combustible gases, you can safely enter the testing area.
Pumped gas detectors can keep you away from areas that may contain potentially harmful gases.
It is not uncommon for ships to be low and over 10 meters in length. In this type of confined space entrance, a pump with a retractable probe allows you to slowly advance into the space using the front probe. This ensures atmospheric safety before the entrance.
At other times, ships may be tall and narrow, requiring entry from above. Using a gas detector with a pump and pipeline, you can check from above whether the entire container is completely free of any harmful gases before entering.
In these two examples, you allow the pump and sampling equipment to suck air into the gas detector before entering, making the operation safer.
We have seen how gas detectors with pumps make operation easier and safer. However, having a pump does not increase the detection range or effectiveness of the gas detector.
Whether you use a gas detector with a pump or a non pumped gas detector, the sensor can only detect the gas in direct contact with them.
Installing a pump on the gas detector will not increase the amount of gas visible to the sensor. On the contrary, the pump allows you to test the atmosphere at a certain distance from the gas detector.
Therefore, if you place two gas detectors side by side, one without a connected pump and the other without a pump gas detector, both can quickly detect harmful gases. Both will read the same.
What are the drawbacks of using a gas detector with an air pump?
Although gas detectors will detect gas in the same way, regardless of whether there is a pump or not, gas detectors with pumps will definitely be larger and heavier.
In addition, the pump will use some gas detector batteries to shorten operating time. Due to the fact that workers typically wear gas detectors throughout the working day, which may extend to more than 12 hours, the importance of using small, lightweight gas detectors that operate throughout the entire shift is self-evident.
Most people agree that it is better to store the gas detector and pump together in an absolutely necessary place.
