Gastec P-5-H Permeation Tube Sulphur Dioxide

GASTEC P-5-H 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 1.1 – 76.4 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-H Permeation Tube Sulphur Dioxide

High Concentration Output: Designed to generate higher concentrations of Sulphur Dioxide ( $1.1 - 76.4$ ppm) compared to the standard P-5-5 model (which only goes up to ~3.6 ppm).
Stable Gas Generation: Contains high-purity liquefied $SO_2$ sealed within a Fluororesin (FEP) membrane. Gas permeates through the wall at a constant rate when heated.
Gravimetric Traceability: The permeation rate is calibrated based on weight loss, ensuring high accuracy for calibration standards.
PD-1 Compatibility: Specifically fits the Gastec Permeater PD-1 series (PD-1B, PD-1C) ovens.
Safety: Provides a safe alternative to high-pressure gas cylinders for generating toxic $SO_2$ gas in a laboratory setting.
