Environics® Gas Dilutors and Gas Dividers automatically generate precise gas standards for rapid multi-point calibration of analyzers. With an accuracy of +/- 1% and repeatability of +/- .05% of setpoint, each system's 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). The calibration data consists of an eleven-point comparison of commanded versus actual flow with linear interpolation between the points. Units are commonly customized for use as Automotive Gas Dividers, VOC Dilutors and Continuous Emissions Monitoring (CEM) Calibrators.

Units can now be ordered or retrofit to run on a 24V power source so you can use your unit anywhere.

Products

The Environics® Series 4040 is a computerized gas dilution system that automatically generates precise gas standards for rapid multi-point calibration of analyzers. The gas mixes can be used in generating precise gas calibration standards, creating gaseous atmospheres or producing gas mixes for analytical research or production purposes. The Series 4040 can produce gas concentrations from percent to parts per billion levels for single or multi-point calibration.

Series 4040

Purity of calibration gases is assured with the Series 4040 Ultra-High Purity (UHP) Gas Dilution System. Manufactured with metal seal MFC’s and orbitally welded joints, the system has minimal dead volume and maintains a low leak rate to prevent atmospheric contamination of gas calibration standards. An ideal system for providing those in the semiconductor, aerospace, research/biotech and advanced materials industries a 20 year history of reliable UHP systems with low upkeep, long lifespan, and high repeatability and accuracy.

Series 4040UHP

The Environics® Automotive Gas Divider is an advanced instrument for the dynamic calibration of automotive or mobile source emissions analyzers. This system stands out from competitors in its ability to generate infinitely varied concentrations within the operating range of the instrument, protecting your investment and giving you the needed flexibility should standards change. Common programs can be saved and scheduled with ease.

Automotive Gas Divider

The Environics® Series 4040 VOC Gas Dilution System is a microprocessor based gas dilution system specifically designed for the preparation of calibration standards used for VOC (Volatile Organic Compounds) monitoring programs. This system stands out from competitors in its ability to generate infinitely varied concentrations within the operating range of the instrument as well as custom features to prevent gas adhesion and our humidification options.

VOC Gas Dilution System

The Environics Continuous Emissions Monitoring Calibration Systems (CEMCS) have been used in CEM vans and laboratories for over twenty-five years.  They meet or exceed the performance requirements of the United States EPA 40 CFR Part 51 Method 205 Appendix M. The accuracy and repeatability make them the unit of choice for source testers around the world.

CEM Calibration System

The Environics® Multi-Gas Calibration/Dilution System is the ideal instrument for dynamic multi-point gas calibration when working with low level gases (<1%). 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 with ozone generation is also available.
