The Series 4000 consists of a single chassis now supporting up to eight mass flow controllers. The mass flow controllers are factory calibrated using a primary flow standard traceable to the United States National Institute of Standards and Technology (NIST). Each flow controller utilizes an 11 point calibration table with linear interpolation, to increase accuracy and reduce flow controller nonlinearity.
Simultaneously mixes up to SEVEN gases in a balance gas at user set concentrations.
Allows multi-point calibration of analyzers.
Automatic calculation of dilution and span gas flows.
Internally-stored Mass Flow Controller calibration tables .
Modular design allows for additional gas circuits to be added.
User definable cylinder library allows for easy selection of frequently used gas cylinders. Each cylinder may contain an unlimited number of component gases, with automatic K-factor calculation.
