1. INTRODUCTION, SPECIFICATIONS, APPROVALS, &
COMPLIANCE
Teledyne API’s Model T300 and Model T300M are Gas Filter Correlation Carbon
Monoxide Analyzers. These microprocessor-controlled analyzers are used to determine
the concentration of carbon monoxide (CO) in a sample gas drawn through the
instrument. The analysis method is based on the Beer-Lambert law, an empirical
relationship that relates the absorption of light to the properties of the material through
which the light is traveling over a defined distance. In this case the light is infrared
radiation (IR) traveling through a sample chamber filled with gas bearing a varying
concentration of CO.
The T300/T300M uses Gas Filter Correlation (GFC) to overcome the interfering effects
of various other gases (such as water vapor) that also absorb IR. The analyzer passes the
IR beam through a spinning wheel made up of two separate chambers: one containing a
high concentration of CO known as the reference, and the other containing a neutral gas
known as the measure. The concentration of CO in the sample chamber is computed by
taking the ratio of the instantaneous measure and reference values and then compensating
the ratio for sample temperature and pressure.
Proprietary software allows configurable data acquisition capability that can be triggered
conditionally or periodically, enabling operators to perform predictive diagnostics and
enhanced data analysis by tracking parameter trends. Reports can be downloaded onto a
USB flash drive or via the I/O ports. Operators can also view real-time graphing with one
touch of the interface screen.

ATTENTION
COULD DAMAGE INSTRUMENT AND VOID WARRANTY
Printed Circuit Assemblies (PCAs) are sensitive to electro-static
discharges too small to be felt by the human nervous system. Failure
to use Electro-Static Discharge (ESD)
protection when working with
electronic assemblies will void the instrument
warranty. Refer to the
manual, Fundamentals of ESD, PN 04786, which can be downloaded
from our website at http://www.teledyne-api.com.
ATTENTION
COULD DAMAGE INSTRUMENT AND VOID WARRANTY
Do not operate this instrument without first removing dust plugs from
SAMPLE and EXHAUST ports on the rear panel.
Note
Teledyne API recommends that you store shipping containers and
materials for future use if/when the instrument should be returned to
the factory for repair and/or calibration service. See Warranty
statement in this manual and Return Merchandise Authorization
(RMA) on our Website at http://www.teledyne-api.com.
Verify that there is no apparent external shipping damage. If damage has occurred, please
advise the shipper first, then Teledyne API.
Included with your instrument is a printed record of the final performance
characterization performed on your instrument at the factory. This record, titled Final
Test and Validation Data Sheet, is an important quality assurance and calibration record
and should be placed in the quality records file for this instrument.
