What is the lowest and highest calibration gas concentrations I can generate with the OVG-4?

This depends on the permeation rate of the tube, the flow and the temperature. The OVG-4 can typically generate calibration gas concentrations from tens of part per trillion (ppt) levels up to tens of part per million (ppm). You can launch the Calibration Gas Calculator to see how to increase and decrease concentrations.
