RESPONSE CHARACTERISTICS OF 2 OXYGEN SENSORS FOR OCEANIC CTDS

Response characteristics of a microhole potentiostatic oxygen sensor a nd a Beckman membrane oxygen sensor were measured in a laboratory over temperatures ranging from 1 degrees to 21 degrees C. The response ter m tau of the microhole sensor changed 1.7-fold over this temperature r ange, and tau of the membrane sensor changed 1.6-fold. For the microho le sensor, the effect of temperature on tau can be modeled as ln tau = -6:5 +/- 1618T(-1). For the membrane sensor the temperature effect on tau can be modeled as ln tau = -5.8 + 2116T(-1), where T is temperatu re in kelvins.
