Description
Gastec P-132-H Permeation Tube Methyl Chloride functions as a secondary standard for generating low-concentration gas mixtures. By utilizing a specialized permeable membrane, the tube releases a constant rate of Methyl Chloride when subjected to a stable temperature and flow, ensuring that your calibration procedures are repeatable and accurate.
One of the significant advantages of using a permeation tube over traditional high-pressure cylinders is the reduction in gas adsorption and loss. Because each tube is manufactured to strict tolerances, it provides a dependable method for verifying the sensitivity and linearity of gas monitoring equipment. Please note that while the standard range is 1.6 – 77 ppm, individual differences in permeation rates may cause slight variations in the actual controllable range for each specific tube.
