Environics units are a powerful tool in the fields of hypoxia, hyperoxia and hypercapnia.  Scientists have successfully used the standard ROBD2 and ROBD3  as well as more tailored S3000 Gas mixers (such as the ReDO2 shown below) for these highly varied projects.

To see some recent research topics that have appeared in peer-reviewed publications, including a recent study entitled, "Uncovering Latent Deficits Due to Mild Traumatic Brain Injury by Using Normobaric Hypoxia Stress" and a review of the potential use of the ROBD2 to evaluate the need for supplmental oxygen in flight for at risk commercial plane passengers, see our research applications page.

Environics systems can be tailored to meet the specific needs of research applications. One example is the RODD, a specialized system developed to help determine if fighter pilots could safely fly soon after Lasik eye surgery. This custom unit allowed researchers to vary oxygen concentration and humidity levels, using manikins equipped with an O₂ sensor in one eye socket and a hygrometer probe in the other. The flexibility of the Environics platform enabled precise control of conditions critical to the study.

Flexibility:  Environics’ systems automatically blend and dilute gases to generate precise oxygen and carbon dioxide concentrations.  Levels can be varied in response to your commands within your target range.

Accuracy: Our gas mixing technology is based on very precise control of thermal mass flow controllers. Normally, thermal mass flow controllers offer an accuracy +/- 1% of full-scale flow. However, when combined with Environics computerization and calibration, this accuracy specification is improved to +/- 1% of setpoint. The Full-scale error vs. Setpoint error document shows the 10x improvement in accuracy of a thermal mass flow controller when using Environics controlling technology.

Oxygen Clean:  We require cleaning of all components for systems that will be subjected to oxygen levels above 25% for safety.

Repeatability:  Our systems have a repeatability of +/-0.05% of full scale.

Traceability:  The instruments' mass flow controllers are factory calibrated using a computer controlled primary flow standard traceable to the United States' National Institute of Standards and Technology (NIST).

Price Savings:  By using pure gases in place of expensive pre-mixed blends, your system will help pay for itself.

Optional Alarms (S3000 only):  An optional visual and/or audible alarm can be installed to alert the operator of specific fault conditions. These alarms can also be emailed to keep you updated even when you are not onsite. This requires the IP address of the email sever have a static IP address.

Custom Options: We have thousands of systems in the field and have developed an extensive library of applications and solutions to meet our customers' needs.   Common options can be reviewed here.
