GASTEC 13TP Operating instructions

  • Hello! I've reviewed the instructions for the Gastec 13TP Carbon Disulphide Detector Tube. This document provides detailed information on its specifications, safe operation, measurement procedures, and interference considerations. I'm ready to assist with any questions you might have about using this detection tube.
  • What is the measuring range of the tube?
    What color change indicates detection?
    What is the recommended sampling rate?
    What interferences can affect the results?
MEASUREMENT PROCEDURE :
If the Automatic Air Sampling Pump Model GSP-300FT-2 or GSP-501FT is used.
