Question 27 of 30
Electrochemical Sensors: identify a key finding for its use on board tankers
A
Electrochemical sensors are based on the fact that cells can be constructed that react with the measured gas and generate an electric current.
B
The Cell current can be measured, and the amount of gas determined.
C
The sensors are low cost and are small enough to allow several to be incorporated into the same instrument, making them suitable for use in multi-gas detectors.
D
There are numerous electrochemical sensors available covering a number of gases which may be present in the shipboard environment.

Answer & Explanation
The correct answer is Option C: The sensors are low cost and are small enough to allow several to be incorporated into the same instrument, making them suitable for use in multi-gas detectors..
Electrochemical sensors are compact, energy-efficient, and can be easily miniaturized, which makes them ideal for inclusion in portable multi-gas detectors used by seafarers for daily safety checks.
