Cal-MAT - Model 4040 Series -Computerized Gas Dilution System
The Matheson Cal-MAT 4040 Series 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 to generate precise gas calibration standards, create gaseous atmospheres, or produce gas mixes for analytical research or production purposes. The Cal-MAT 4040 can produce gas concentrations from percent to ppb levels for single or multi-point calibration. The system consists of two components, the 4040 Series instrument and the user’s personal computer. The user interface is a Microsoft Windows application that communicates with the Cal-MAT system via an RS-232 serial interface. The Cal-MAT 4040 consists of a single chassis supporting up to four mass flow controllers. Two mass flow controllers are standard; additional mass flow controllers may be ordered as options.
- Broad range of dilution ratios (up to 1,000:1) allows the user to significantly reduce the number of cylinders needed to perform compliance tests
- Modular design allows for additional circuits to be added,increasing system flexibility
- Internally stored mass flow controller calibration tables improve accuracy
- 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
The Windows based software for the Cal-MAT 4040 offers four basic modes of operation:
- Concentration Mode: Allows the user to create a blend by entering the target gas concentrations for each source gas cylinder and the desired total output flow for the mix.
- Divider Mode: Allows the user to operate the instrument as an automated ten step gas divider
- Flow Mode: Allows the user to specify the flow rate of each gas cylinder
- 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.
