For use with the Permeation Calibration System.
The permeation tubes are teflon / PTFE tubes filled with a specific component in a liquid-vapor phase. The permeation rate of the tube is a direct function of the temperature.
Tubes are supplied with a Certificate of Calibration showing permeation rate in ng/min plus expected useful lifetime of the permeation …more

Permeation Calibration System
The calibration gas generator from dot-red uses the technology of permeation. The permeation tubes are Teflon tubes filled with a specific component in a liquid-vapor phase. The permeation rate of the tube is a direct function of the temperature. With the dot-red calibration gas generator, a large scale of concentrations can be reached by changing the temperature or by modifying the dilution air flow. The device automatically calculates the flow in dependence of the requested final gas concentration.
External Ultra Zero Air generator is required to dilute what is going out of the permeation oven.
Combined Pure Air / H2 Gas Generator
The Pure Air / H2 is a combined Hydrogen and Pure Air Generator. The Hydrogen Generator employs the newest PEM membrane technology available for electrolytic production of pure hydrogen gas. Only pure water, either distilled or deionized, is required to provide trouble free long-term operation. The no maintenance static dryer has replaced the Molecular Sieve …more
