Environics Gas Diluters & Dividers

Environics Gas Diluters & Dividers

The Environics® Series 4040 is a computerized gas dilution system that automatically generates precise gas standards for rapid multi-point calibration of analyzers. 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 4040 can produce gas concentrations from percent to ppb levels for single or multi-point calibration, allowing you to use fewer cylinders.

Concentration: ± 1.0% setpoint
Flow: ± 1.0% setpoint
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)
