The fiber/coax power meter is employed to measure both, the laser power transmitted through the fiber optic cable (for fiber optic cable verification) and the return signal as seen directly by the IR detector (for optimizing alignment). The meter is required for measurements at specific wavelengths.  The meter is an essential tool for checking system components and should remain on site with the equipment.

External audit modules allow the client to check the performance of the analyzers by automatically inserting a sealed cell containing the target gas into the measurement path.  The sealed gas cell contains small amount of target gas (20-500 ppm-m available) and is warranted for 3 years. 

The cells can be connected in two configurations:  a fiber-fiber device that simply inserts into the fiber optic cabling (in series with the optics) at the analyzer, as well as fiber-coax device that can be independently connected to the analyzer (without the need of external optics).  The client is required to manually insert the cell into the fiber optic cabling.  The client may get the audit module re-certified by Unisearch at an added cost

The external audit module allows the client to check the performance of the analyzers by inserting a module containing a flow-through cell and gas-in/gas-out ports. The gas-in port is meant to be connected to a gas cylinder containing known levels of the target gas.  Cylinder standard gas, flow control and sampling lines to the audit cell from the cylinder, and for exhaust disposal are the responsibility of the client.  

The audit module inserts into the fiber optic cabling (in series with the optics) at the analyzer.  The user simply flows calibration gas from a standard source (cylinder, permeation device) though the cell and determines the equivalent concentratioon from the ratio of the measurement path lenght to the audit cell path length times the calibration gas concentration.
