The Environics® Series 2020 Gas Dilution System automatically generates precise gas standards for rapid multi-point and multi-scale calibrations. This system stands out from competitors in its ability to generate infinitely varied concentrations within the operating range of the instrument, protecting your investment and giving you the needed flexibility should standards change.
The Series 2020 precisely dilutes high concentration Protocol-1 or certified gas cylinders to an infinitely variable range of concentrations from high percents to low parts per million. The instrument meets or exceeds the performance requirements of the new United States EPA 40 CFR Part 51 Method 205 Appendix M.
The instrument's mass flow controllers are factory calibrated using a computer controlled primary flow standard traceable to the United States' National Institute of Standards and Technology (NIST). The calibration data consists of an eleven-point comparison of commanded versus actual flow with linear interpolation between the points.
