GASTEC P-5-5 Permeation Tube Sulphur Dioxide
Although technology is always evolving, one demand for our products never changes: the demand for customer safety. Whenever we contribute to customer safety, we are presented with an opportunity to develop further. GASTEC holds this corporate creed of safety and development in high esteem, as it strives to grow while always putting customer safety first.

Generating calibration gas with a permeation tube.
Concentration range 0.04 – 3.6 ppm.
*As Permeation tubes have individual differences in permeation rates, the above concentration ranges may differ slightly from the actual range that can be controlled.
Key Features of Gastec P-5-5 Permeation Tube Sulphur Dioxide
Stable Gas Generation: Uses a high-purity chemical sealed inside a permeation membrane (FEP). When heated to a constant temperature, the gas permeates through the membrane at a stable, controlled rate.
Gravimetric Traceability: The permeation rate is determined by the weight-loss method, ensuring high accuracy for calibration standards.
Safe Handling: Unlike high-pressure gas cylinders, permeation tubes contain a very small amount of chemical, making them safer to store and transport.
PD-1 Compatibility: Specifically designed to fit into the Gastec Permeater (PD-1B, PD-1C) oven for precise temperature control.
Long Shelf Life: Typically stable for up to 3 years from manufacture (if stored correctly) or until the liquid chemical inside is depleted.
