Take it with you wherever you go and responsible for their own safety and also to reassure their families safetyMain difference between fuel cell alcohol tester and semi-conductor alcohol tester
1.The fuel cell sensor material is a chemically-reactive fuel cell type (the sensor sheet reacts with the alcohol molecule to generate a weak current signal), and is the same as the sensor sheet of the high-precision alcohol tester used by the traffic police.
Fuel cell sensor processing circuit is complex, but the instrument sensitivity, accuracy, feature recovery speed(characteristic zero speed), stability (characteristic drift), long life, test results close to police standards.
2.The sensing material of the semi-conductor sensor is a physical semi-conductor oxide SnO2 (inductive alcohol
molecule, whose internal resistance value changes), and the overall sensitivity, accuracy, stability (characteristic drift) is smaller than that of electrochemistry, but at a low concentration When the concentration is less than 0.25mg/L.
the accuracy is equivalent to that of electrochemistry, which can meet the requirements of the civil grade standard.
The semi-conductor processing circuit is relatively simple and small in volume. Compared with electrochemistry, the semi-conductor sensor has a short life. But the priceis low, easy to carry, widely used in private civilian grade.
