Environics gas mixing and delivery systems are widely used by both sensor developers and manufacturers. Designed for versatility and precision, our systems are ideal for sensor R&D as well as high-throughput production screening and sorting. Whether in the lab or on the production floor, Environics systems provide an efficient, reliable solution for consistent gas delivery and testing.

Each Environics system is tailored to your specific research or production needs to reliably generate accurate and repeatable results.

Our most popular systems used by sensor developers and manufacturers are:

The Series 3000 Gas on Demand system is 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. Systems can be designed with alarms and other options such as ballast tank filling (on-demand), datalogging, and remote communication.

The Series 4040 is a gas dilution system designed to produce a wide range of gas concentrations by diluting a target gas in a balance gas. The system is controlled through an intuitive Microsoft® Windows application, with standard USB connectivity (optional RS232 or Bluetooth communication).

Two examples of sensor R&D and testing configurations using the Environics S4040.

Accuracy: Our technology is based on very precise control of thermal mass flow controllers.  With our standard flow range, systems are capable of taking a high concentration or pure 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 (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.
