Cylinders of calibrated O2 gas traceable to NIST-Standard Reference Material
specifications (also referred to as SRMs or EPA protocol calibration gases) are
commercially available.
Table 9-1: NISTSRM's Available for Traceability of O2 Calibration Gases
NIST-SRM Type Nominal Concentration
2657a O2 in N2 2%
2658a O2 in N2 10 %
2659a O2 in N2 21%
2619a1 CO2 in N2 0.5%
2620a1 CO2 in N2 1%
2622a1 CO2 in N2 2%
2624a1 CO2 in N2 3%
2744b1 CO2 in N2 7%
27451 CO2 in N2 16%
1 Used to calibrate optional CO2 sensor.
Note For span point calibration it is generally a good idea to use 80% of the reporting
range for that channel. For instance, if the reporting range of the instrument is
set for 5%, the proper span gas would be 4%.

A strip chart recorder, data acquisition system or digital data acquisition system
should be used to record data from the serial or analog outputs of the T802.
