Gastec P-92-1 Permeation Tube Acetaldehyde

A high-precision Acetaldehyde permeation tube used for generating known gas concentrations. It is optimized for use with the Gastec PD-2 Gas Permeation Device or similar dynamic calibration systems.

Description

The P-92-1 contains liquid Acetaldehyde. When placed in a temperature-controlled oven, the chemical permeates through the tube’s wall at a predictable, repeatable mass-flow rate. By mixing this small amount of gas with a controlled flow of dry diluent gas (air or nitrogen), you can create accurate calibration standards in the parts per million (ppm) range.

Although, technology is always evolving, one demand on 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.

Features

  • Consistent Output: Eliminates the “concentration decay” often found in reactive gas cylinders, where the gas reacts with the cylinder walls.
  • Traceable Accuracy: Each tube is individually calibrated by weight-loss measurements, ensuring that your gas standards are highly accurate and repeatable.
  • Adjustable Concentration: By fine-tuning the oven temperature or the diluent flow rate, you can generate a wide range of concentrations with a single tube.
  • Safe and Small: Contains only a minute amount of Acetaldehyde, making it much safer to handle and store than large, high-pressure cylinders.
  • Long Shelf Life: When stored correctly, the P-92-1 remains stable for several months of active calibration use.
