Environics ® Product Data Series 4000 Multi-Component Gas Mixing System A low cost, multi-component gas mixing system with an advanced Windows user interface. The Environics Series 4000 is a multi-component gas mixing system that automatically mixes up to three individual gases in a balance gas. 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 4000 can produce gas concentrations from percent to ppb levels for single or multi-point calibration. The system consists of two components: the Series 4000 instrument and the user’s personal computer. The user interface is a ® Microsoft Windows application that communicates with the Environics system via an RS232 serial interface. The Series 4000 consists of a single chassis supporting up to four mass flow controllers. The mass flow controllers are factory calibrated using a primary flow standard traceable to the United State's 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. PRODUCT FEATURES AND BENEFITS INSTRUMENT OPERATION Simultaneously mixes up to three gases in a balance gas at user set concentrations. The Series 4000 has three basic modes of operation. Allows multi-point calibration of analyzers. Automatic calculation of dilution and span gas flows. Concentration Mode: Allows user to create a blend by entering target gas concentrations for each source gas cylinder, and the desired total output flow for the mix. Internally-stored Mass Flow Controller calibration tables . Flow Mode: Allows user to specify the flow rate of each gas cylinder. Modular design allows for additional gas circuits to be added. User definable cylinder library allows for easy selection of frequently used gas cylinders. Each cylinder may contain an unlimited number of component gases, with automatic K-factor calculation. Program Mode: Provides the ability to program the instrument for unattended operation. Programs can be recalled and run in any sequence, at various times/dates.

Operating temperatures 32 - 104 F (0 - 40 C) SPECIFICATIONS Performance Accuracy Concentration: Flow: Flow Repeatability: Performance temperatures 59 - 95 F (15 - 35 C) ± 1.0% setpoint ± 1.0% setpoint ± 0.05% setpoint * Performance specifications are valid when all Mass Flow Controllers are operating between 10% and 100% of full scale flow. Mass flow controllers are calibrated using a NIST traceable Primary Flow Standard, using a Reference Temperature of 0 o C (32oF) and a Reference Pressure of 760 mm Hg (29.92 in. Hg) Warm up time: 30 minutes Mechanical Inlets External ¼" Swagelok™ (or...
