Gas sampling counter manufactures analyze or detect the concentration of air. These are some important features of a gas sampling pump.
- Piston: A slim and wide piston which ensures a tight grip
- Tip breaker: For convenient snapping of tubes
- Slow finish Indicator: It includes a built-in indicator that automatically tells you when strokes are complete.
- Tubes: It includes many tubes which have different reagents in it to check the concentration of various gases.
- Manual: You get a manual in which you can find the number of strokes a particular tube requires.
Why are they used?
- They are intrinsically safe to use.
- They are pre-calibrated and you just need to set the number of strokes you need.
- They are not very expensive and you can easily get them online.
- They can detect the concentration of many gases which are difficult to measure otherwise.
- The gas sampling counter manufactures are heavy-duty, compact and very easy to use.
- Initiate a leak test because if the pump has leaked it may show inaccurate readings.
- For checking a leak, take an unopened tube, and pull the piston until you hear a click sound. If the indicator does not light that means that your pump is not having any leaks.
How to take a sample and check its concentration?
- Select a tube according to the type of gas you want to check the concentration
- Insert it in the tip breaker, score it and then snap it. Do the same procedure for both sides.
- Insert the tube in the rubber pump. Remember to keep the arrow on the tube pointing towards the pump.
- Now, you need to select the number of strokes required to determine the concentration of the gas. For this check, the manual provided in the kit.
- If you want a full stroke then rotate the marker to a 100 and then pull the piston until you hear a click sound.
- Now the pump is drawing the gas from the tube and making a vacuum inside it.
- Now you have to wait for a minute or two until you see the indicator getting lighted.
- As soon as the indicator lights up, take the tube out of the pump. Check the scale and notice a color change in the reagent inside the tube. Note down the reading till where the color has changed
- And the value you just noted is the part per million concentration of that gas.
