Gastec P-71-5 Methyl Mercaptan Permeation Tube

Description

Maintaining the accuracy of gas sensors requires a consistent and known concentration of the target gas. The Gastec P-71-5 Permeation Tube Methyl Mercaptan achieves this by utilizing a permeable membrane technology. The liquefied Methyl Mercaptan inside the tube permeates through the wall at a constant rate when maintained at a stable temperature.

This method is superior to traditional gas cylinders for low-concentration applications, as it eliminates the issues of gas adsorption and degradation often found in high-pressure containers. By controlling the flow rate of the diluent gas and the temperature of the tube, users can achieve highly specific concentrations within the 0.007 to 1.52 ppm range. Note that since individual tubes may have slight variations in permeation rates, each unit is calibrated to provide precise performance for critical industrial monitoring.
