How does a toxic and flammable gas detector work?

Reply #22018-09-24

Toxic sensors are generally of the electrochemical type, while those for detecting flammable gases are usually of the catalytic combustion type; therefore, sensors generally need to be replaced every 18 months or so (the exact timing requires calibration to determine). At present, these sensors are subject to mandatory inspection, with checks being carried out once a year.
