How to Use Gas Sampling Pump GV100S/GV100LS/GV110S.
Prepare Pump
01- Insert the detector tube into the pump inlet.
- Break off both tube tips before insertion.
Take Sample
02- Pull the handle back fully to draw one stroke (100 mL).
- Use multiple strokes if required, depending on test conditions.
Read Results
03- After the required sampling strokes, remove the tube.
- Compare color change with scale markings to determine concentration.
Airtightness Check
Before you begin sampling, it’s crucial to verify that your sampling pump is airtight—any leaks can compromise measurement accuracy. Here’s a simple check to ensure reliability:
Secure the Inlet
Ensure the inlet nut is firmly tightened
Insert Intact Tube
Place a detector tube (with both tips intact) into the pump’s rubber inlet
Align Marks
Push the handle fully in, aligning the guide marks (red line on pump body and triangle on handle)
Lock & Hold
Pull out in one motion until locked. Wait approximately 1 minute.
Perform the Test
Twist handle 90°, then release gently. The handle should smoothly return—if the red mark is fully concealed, the pump is airtight.
