GASTEC 13TP Operating instructions

Brand: GASTEC

Model: 13TP

Type: Operating instructions

GASTEC 13TP is a detector tube designed to measure Carbon disulphide levels in air. It is suitable for various applications, including industrial and environmental monitoring. The device offers a measuring range of 0.05 to 2.4 ppm and a detection limit of 0.04 ppm. It utilizes a colorimetric reaction to indicate the presence of Carbon disulphide, with a blue reagent turning yellowish-green upon exposure to the gas.

MEASUREMENT PROCEDURE :

If the Automatic Air Sampling Pump Model GSP-300FT-2 or GSP-501FT is used.
