The KIN-TEK Analytical 491Flex™ Gas Standard Generator System is composed of one or more manually-operated modules, depending on application requirements.
491Flex™ Modules can be packaged in stand-alone carrying cases or packaged in one or two 3-module expansion cases. Unused module slots in the expansion cases are filled with blank panels. The modules are electronically connected to each other by a short cable on the rear panel.
491Flex™ Base Module
The “Base” module is required in every 491Flex™ system. This module provides:
- Manual front panel
- Oven temperature setpoint and primary dilution flow rate adjustment controls
- Standby, zero and span selection
- Permeation tube oven temperature and primary dilution mass flow rate digital readout

491Flex™ Auxiliary Permeation Oven Module (PM)
The PM provides additional permeation tube ovens to allow generation of a multi-component gas stream for cases in which;
- tubes must be maintained at different temperatures
- differing permeation technologies (disposable tubes vs. refillable tubes) are required
- more components are needed than can be held in a single oven, or
- for applications in which various components will be switched in and out of the gas stream.
One PM oven module can be added wherein each oven can hold up to eight disposable permeation tubes or one factory-refillable tube. Any combination of ovens can be kept on standby to keep various tubes at temperature while not adding their emission to the output gas stream.

491Flex™ SD Secondary Dilution Module (SD)
The SD Module extends the range of concentration attained from permeation tubes by providing an additional stage of dilution of the gas stream. Very low concentrations – ppb or ppt – can be generated depending on the emission rate of the tubes and the flow rate range of the primary and secondary dilution flow controllers. Overall dilution ratios of 10,000:1 can be achieved.

The SD module extends the range of concentration attained from permeation tubes by providing an additional stage of dilution of the gas stream. Very low concentrations – ppb or ppt – can be generated depending on the emission rate of the tubes and the flow rate range of the primary and secondary dilution mass flow controllers.
