Question 87 of 200 tasco Exam
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.
Correct
D There are numerous electrochemical sensors available covering a number of gases which may be present in the shipboard environment.
Answer & Explanation
