🔍 Key Concepts

• Combustible gas indicator (CGI) basic operating principle • How catalytic sensors detect flammable gases in a sample of air • Why the instrument needs an element that reacts measurably when exposed to flammable vapor

💭 Think About

• Think about which choice describes something that can change its electrical properties when exposed to a flammable gas or vapor. • Ask yourself which option is typically used inside small electronic sensors that can be read by a meter or circuit. • Consider which answer best fits an "intricate instrument" used repeatedly and calibrated, rather than something that is consumed or used up each test.

✅ Before You Answer

• Identify which option is commonly associated with electrical sensors and electronic detection equipment. • Eliminate any choices that sound like they would be used up or chemically destroyed with each test, making them impractical for routine gas monitoring. • Check which device part could be heated and monitored so that a change in temperature or resistance indicates gas presence.
