    ETG CAL-G 100

    Precise Gas Calibrator with Permeation Oven


    ETG's Model CAL-G-101 Permeation oven is a simple, effective tool for generating precise gas concentrations for calibrating air quality analyzers, source monitors and other instruments. When combined with ETG's Gas Dilution Calibrators, it creates a powerful and intelligent calibration system.


    The Model CAL – G - 101 Permeation oven chamber is large enough for a variety of tasks and was designed to be used in a number of different settings.


    Operators can use many types and sizes of permeation tubes concurrently in the Model CAL – G – 101’'s large-capacity gas permeation chamber. A front panel mounted precision pressure regulator, reference pressure gauge,temperature controller and oven inlet give the operator easy access to the unit controls at all times

     

    The most common type is a small tubular device that has liquid analyte sealed inside the tube. A very small but stable flow (nanograms-per-minute) of analyte vapor is emitted through the tube wall at constant temperature. The emission rate of the tube is determined by measuring the rate of weight loss.

     

    Permeation tubes use a permeable membrane   to dispense a small flow of chemical vapor
