EPA Calibration Protocol 
Teledyne API – Model T300/T300M CO Analyzer 
232 
The reliability and usefulness of all data derived from any analyzer depends primarily 
upon its state of calibration.  To ensure accurate measurements of the CO levels:  
1.  The analyzer must be calibrated at the time of installation and recalibrated as 
necessary.  
2.  In order to insure that high quality, accurate measurement information is obtained at 
all times, the analyzer must be calibrated prior to use.   
3.  Calibrations should be carried out at the field-monitoring site.   
4.  The analyzer should be in operation for at least several hours (preferably overnight) 
before calibration so that it is fully warmed up and its operation has stabilized. 
5.  If the instrument will be used on more than one range, it should be calibrated 
separately on each applicable range.  
6.  Calibration documentation should be maintained with each analyzer and also in a 
central backup file. 
7.  The true values of the calibration gases used must be traceable to NIST-SRMs See 
10.1.2. CALIBRATION EQUIPMENT, SUPPLIES, AND EXPENDABLES 
The measurement of CO in ambient air requires a certain amount of basic sampling 
equipment and supplemental supplies.  The Quality Assurance Handbook Section 2.6 
contains information about setting up the appropriate systems. 
10.1.2.1. DATA RECORDING DEVICE 
Either a strip chart recorder, data acquisition system, digital data acquisition system 
should be used to record the data from the Mode; T300 RS-232 port or analog outputs.  
If analog readings are being used, the response of that system should be checked against 
a NIST referenced voltage source or meter.  Data recording device should be capable of 
bi-polar operation so that negative readings can be recorded. 
10.1.2.2. SPARE PARTS AND EXPENDABLE SUPPLIES 
In addition to the basic equipment described in the Q.A. Handbook, it is necessary to 
maintain an inventory of spare parts and expendable supplies.  Section 11 describes the 
parts that require periodic replacement and the frequency of replacement.  Appendix B 
of this Technical Manual contains a list of spare parts and kits of expendables supplies.
