Series 4000/4040 (Multi-Component Gas Mixing or Dilution System) 

A low cost, multi-component gas mixing system with an advanced Windows user interface, the Series 4000 has the capability of mixing up to seven individual gases in a balanced gas.  The S4040 dilution system allows you to dilute individual cylinders in a balanced gas at ratios from 1:1 up to 30,000:1 (or more in a custom configuration). Units come to standard with USB. The gas mixes/dilutions can be used in generating precise gas calibration standards, creating gaseous atmospheres or producing gas mixes for analytical research or production purposes. The Series 4000 can produce gas concentrations from percent to ppb levels for single or multi-point calibration.
