1.	The micro-electrode is enclosed in a water jacket with circulating water at a constant temperature of ___________ °C for determination of pH.(a) 25(b) 34(c) 38(d) 42The question was posed to me in an international level competition.This is a very interesting question from Spirometry topic in division Pulmonary Function Analysers of Biomedical Instrumentation
Answer» RIGHT option is (c) 38 Easiest explanation: A micro-ELECTRODE for CLINICAL APPLICATIONS requires only 20–25 ml of capillary blood for the determination of pH. The electrode is ENCLOSED in a water jacket with circulating water at a constant temperature of 38°C. The water contains 1% NACI for shielding against static interference.
