Gas Mixers for Sensor Screening and Research Systems
Environics gas mixing and gas delivery systems are used extensively by sensor development companies as well as sensor manufacturers. Our systems are ideal for production screening (sorting) of sensors as well as research and development. The Environics systems are an efficient and versatile piece of laboratory equipment.

Each system is a custom built, computerized, mass flow controller based systems which allow you to automatically blends and dilutes gases to generate precise gas mixes for your analytical research or production purposes.Our most popular mixing systems used by sensor developers and manufacturers are:

The Series 3000 Gas on Demand system is a computerized gas panel system and is usually used to dynamically produces and delivery mixes containing two or three gases, though more complex mixtures can also be created.  The main controls of the system are HMI (Human Machine Interface); color touch screen and PLC combined.

The Series 4000 is a multi-component gas mixing system that automatically mixes up to three (3) individual gases in a balance gas.  The user interface is a Microsoft® Windows application that communicates with the Environics system via a USB interface.

Accuracy: Our technology is based on very precise control of thermal mass flow controllers.  The mixing systems are capable of taking a high concentration cylinder of span gas and blending it with a balance gas to produce percent, ppm, ppb and ppt level standards, all to ±1% set point accuracy.  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.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:  An optional visual and/or audible alarm can be installed to alert the operator of specific fault conditions. NEW FEATURE! 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. Contact Us for more information on this exciting new feature!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 include: an  RS-232 Serial Data Interface, Permeation Ovens, Purge Circuit, Status Board, Heated Gas Handling System, or Extra Component Gas Inlet Ports.  

About Environics - World Leader in Gas Mixers, Gas Dilution and Calibration Systems
Environics is a world leader in computerized gas flow instrumentation. Our headquarters for design, manufacturing, sales and service is located in a modern 11,000 square foot facility in Tolland, Connecticut. We are ISO 9001 certified, having received ISO 9001 Quality Systems Certification in April, 1997.

All service is handled factory direct. Sales are handled direct and by selected manufacturers representatives and distributors worldwide

Environics Technology
Our gas mixing technology is based on very precise control of thermal mass flow controllers (MFCs). Normally, thermal MFCs 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 MFC when using Environics controlling technology. Our calibrators and dilution systems exceed the accuracy required by the EPA for Ambient Calibrators (ref: Method 205, 40CFR51, 40CFR60, 40CFR75). For more technical information, see our Technical Documents section, which contains current articles and CFR's pertinent to our technologies.

We encourage you to challenge us with your most difficult requirements. We specialize in custom systems. We have thousands of systems in the field and have developed an extensive library of applications and solutions to meet our customers' needs. The application of our technology has enabled us to become the world leader in user-friendly computerized gas flow instrumentation.
