Environics Gas Mixers & Blenders

Environics Gas Mixers & Blenders

The Environics® Series 4000 is a multi-component gas mixing system that automatically mixes up to three individual gases in a balance gas. The gas mixes 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.

Concentration: ± 1.0% setpoint
Flow: ± 1.0% setpoint
Flow Repeatability: 0.05%

Warm up time: 30 minutes

* Performance specifications are valid when all Mass Flow Controllers are operating between 10% and 100% of full scale flow.  Mass flow controllers are calibrated using a NIST traceable Primary Flow Standard, using a Reference Temperature of 0°C (32°F) and a Reference Pressure of 760 mm Hg (29.92 in. Hg).
