Gas Mixers and Gas Blenders

Gas Mixers and Blenders


Environics® Gas Mixers and Gas Blenders automatically blend gases to generate precise gas calibration standards, create gaseous atmospheres or produce gas mixes for research or production purposes. Each component concentration may be independently varied.

With an accuracy of better than +/- 1% and repeatability of +/- .05% of setpoint, the Series 4000 can produce concentrations from percent levels to ppb for single or multi-point calibration.


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.

Series 4000

The Environics Series 4000 UHP Gas Mixing System combines the accuracy and repeatability of the Series 4000 with a welded, Ultra-High-Purity (UHP) construction. All units are optimized for your target gases. With all metal seals, units are commonly used for both research & development and/or production applications, including calibration of analytical tools that detect impurities in semiconductor gases. Common features include pressure regulation, canister filling and liquid filled or disposable permeation tubes.  Their small size, low cost of maintenance and longevity have made them the system of choice for over 20 years.

Series 4000 UHP

The Series 6100 automatically performs zero, precision, span and multi-point calibrations using NO, NO2, SO2, CO, hydrocarbons and more. Custom options can be selected for calibration of ammonia, HCl and a variety of other gases of interest. The S6100 is a great option for dilutions from ppm or lower level cylinders. Units can be ordered or retrofit to run on a 24V power source

New options include a Purge feature and the ability to include up to 6 span port. Contact us for more information!
