1.	Which of the following is not a component of solid state sensor used for detection of hydrogen sulphide?(a) Heater(b) Thermistor(c) Semiconductor film(d) Photo detectorThe question was posed to me in my homework.This interesting question is from H2S Analysers topic in section Industrial Gas Analysers of Analytical Instrumentation
Answer» Right ANSWER is (d) Photo detector To explain I would SAY: For measuring H2S, the sensor MUST be maintained at a particular temperature. This is DONE by using a HEATER. The temperature is monitored using a thermistor.
