Linearity
Wherever possible, linearity for the OPTI CCA-TS2 measurement has been established against reference
materials or methods. The linearity of the pO
2
sensor on the OPTI CCA-TS2 has been established versus
the same sensor on the OPTI CCA-TS using whole blood samples tonometered with different %O
2
gas
mixtures to establish the correlation.
