Purity of calibration gases is assured with the Series 4020UHP Ultra-High Purity Gas Mixing/Diluting 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.

A S4020UHP gas mixing system has the expanded capability of both diluting with a balance gas and mixing up to seven individual gases in a balance gas. The standard unit also comes with USB. 

The gas mixes and dilutions can be used in generating precise gas calibration standards, creating gaseous atmospheres or producing gas mixes for analytical research or production purposes. The Series 4020UHP can produce gas concentrations from percent to ppb levels for single or multi-point calibration of single or multi-gas blends.

The system consists of two components: the Series 4020UHP instrument and the user's personal computer. The user interface is a Microsoft® Windows application that communicates with the Environics system via a USB (standard) or RS232 serial interface. Bluetooth enabled devices running Windows software can also control the unit remotely (optional).

Additional options include the ability to remote start, remote stop, and canister filling stop all via a dry contact closure. Optional alarms available and can include visual alarms upon low input cylinder pressure.

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

The Series 4020UHP 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.
