Gastec P-74-H Permeation Tube Dimethyl Sulphide

Gastec P-74-H Permeation Tube Dimethyl Sulphide

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 – 6.3 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.

Features

• Stable Low-Level Generation: Capable of producing a concentration range of 0.04 to 6.3 ppm, making it ideal for calibrating highly sensitive detectors.

• Osmosis-Based Precision: Uses the principle of osmosis through the tube wall. When kept at a fixed temperature, a specific quantity of gas permeates at a constant rate.

• High Reliability: Concentration is determined by measuring basic physical quantities—weight loss of the tube over time and the quantity of dilution gas—ensuring high gravimetric accuracy.

• Broad Application: Essential for calibrating equipment used in odor monitoring (DMS has a characteristic “cooked cabbage” smell), pulp and paper mill emission testing, and wastewater treatment analysis.

• Multi-Tube Capability: Designed to fit Gastec Permeaters, which can often hold multiple tubes (standard size 10 pcs, H-size 5 pcs) for complex calibration tasks.
