Gastec PD-1B-2 Permeater

Description

Gastec PD-1B-2 Permeater achieving accurate results for gas detector calibration requires a standard that is both stable and verifiable. The Gastec PD-1B-2 Permeater utilizes a dynamic method to determine concentration levels by calculating the weight loss of permeation or diffusion tubes over time. This scientific approach ensures that even highly reactive gases, such as chlorine, hydrogen sulphide, or ammonia, can be generated with consistent precision.

The system provides exceptional thermal stability and flow control, which are critical for maintaining a steady permeation rate. By keeping the tube at a fixed temperature and infusing a constant quantity of dilution gas, the device enables a continuous supply of gas standards for longer durations. Whether working with organic solvents or inorganic gases, the Gastec PD-1B-2 Permeater offers a wide range of concentrations to meet diverse industrial and laboratory requirements.
