A(n) ______ analyzer is an oxygen analyzer that uses paramagnetism to measure oxygen concen-tration

a. Galvanic c. Paramagnetic
b. Electrical d. Polarographic

ANS: C
The paramagnetic analyzer uses the physical principle of paramagnetism to measure oxygen con-centration. Galvanic and polarographic analyzers use chemical reactions to measure oxygen con-centration, and electrical analyzers use thermal conductivity.
