AP-20S is an easy-to-operate sampling pump for colorimetric tubes to enter the air sample inside the tube according to the specification of the colorimetric tube by means of a manual piston system. It is a necessary tool to ensure the proper functioning of colorimetric tubes since it enters the exact sample volume required by the tube to react and give the result:

  • Manual piston pump for use with Sensydine colorimetric tubes.
  • 100 ml internal piston volume
  • Warning system to indicate that the tube has absorbed the injected volume
  • System to safely break tubes and be able to measure
  • Easy operation and low cost
