Answer :
Final answer:
Electric gas detectors provide instantaneous readings of gas concentrations, making them essential for real-time monitoring. Unlike other instruments, they give immediate feedback necessary for quick decision-making. Understanding the differences among gas detection tools is crucial for selecting the right one for safety applications.
Explanation:
Understanding Gas Detection Instruments
Gas detection instruments are essential tools used for monitoring the concentration of various gases in the environment. Among the options provided, the instrument that gives instantaneous readings of relative concentration is the electric gas detector.
Electric gas detectors utilize sensors to detect the presence of specific gases and provide real-time readings. These instruments are commonly employed in various industries to ensure safety and compliance with health standards. They are capable of quickly responding to changes in gas concentrations, which is crucial for immediate decision-making in case of potential hazards.
Here are the differences between the various types of gas detection instruments:
- Gas detector tubes: These tubes require manual sampling and provide a reading after a specific time, making them less instantaneous.
- Electric gas detectors: Provide real-time readings and are suitable for immediate response.
- Fixed gas monitors: Typically used for continuous monitoring but may not always offer instant readings depending on the setup.
- Personal sampling devices: Used for specific sampling and may not provide continuous or instant readings.
In summary, if an immediate reading is necessary, electric gas detectors are the preferred choice.
