Environics Series 4020 gas dilution system
Gas dilution system
Product range: Gas Blending & Dilution
Overview
The Environics® Series 4020 can mix up to seven (7) component gases simultaneously to generate precise gas calibration standards and gaseous atmospheres in a broad dynamic range. The dilution capabilities of the Series 4020 allows dilution ratios from 1:1 to 10,000:1 (with larger ranges possible, depending on the configuration of the system). It provides a low cost, computerized gas mixing/dilution system which utilizes an advanced Windows-user interface.
PERFORMANCE
Accuracy
Concentration: ± 1.0% setpoint
Flow: ± 1.0% setpoint
Repeatability: ± 0.05% setpoint
*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)
