Gastec Generating calibration gas with a diffusion tube

Generating calibration gas with a diffusion tube A diffusion tube is a glass tube that consists of a liquid containing portion and a diffusing portion with a uniform inner diameter. A pure target liquid is put into the liquid container using a glass syringe. The liquid must have a vapour pressure of 5 to 400 … Continue reading Gastec Generating calibration gas with a diffusion tube

Calibration gas generating equipment Generating Calibration gas with a permeation tube A permeation tube is a fluororesin tube that contains high-grade liquefied gas. When the tube is exposed to a certain temperature, liquefied gas penetrates the tube wall by osmosis in time-increments enabling a specific quantity of gas to be retained in the tube . … Continue reading Calibration gas generating equipment Gastec

Gastec Calibration Gas Generating Equipment PD-1B And PD-1B-2

Calibration gas generating equipment  The Permeater is a gas generator for calibration purposes that utilises permeation and diffusion tubes to generate the calibration gas. When the permeation and diffusion tubes are set at a constant temperature, the weight of both the permeating and the evaporating diffusion gas will be respectively set at constant levels.In this … Continue reading Gastec Calibration Gas Generating Equipment PD-1B And PD-1B-2
