Abstract

An inspection device for gas fumes consisting of a measure sensor (1), suitable for displaying the amount of gas concentrated in the air, a reference sensor (2), suitable for generating a sample signal to stabilise calibration, a cyclic signaller (7) to compare the signals from both sensors (1, 2) and control, when the signal from the measuring sensor supersedes the calibration value, an electronic sensor (8) whose changing state determine whether an alarm (10) should be sounded.
