Basic Use of Toxic Gas Detectors
Today
we come to understand the selection principles of harmful gas detectors. First
of all, we need to clarify the purpose of monitoring. Generally speaking, there
are two purposes for using harmful gas detectors, one is to detect explosions,
and the other is to detect poisons. The explosion test is to detect the
presence of flammable gas in the operating environment or dangerous occasions.
When the flammable gas exceeds the standard, an alarm is issued to avoid the
occurrence of the explosion: for the test of poison, the content of toxic gas
in the gas is exceeded. Call the police to prevent poisoning of personnel.

Because
the toxic gas detector can display the concentration of various gases, pay
attention to the regular calibration and detection of the toxic gas detector.
In addition, there is a problem that the toxic gas detector will wait for a
long time before obtaining the accurate test value. If the toxic gas detector
is not calibrated and tested in time, it will affect the final Detection value.
Generally
speaking, the gases in dangerous places are generally divided into three
situations, non-toxic or low-toxic and flammable; non-combustible and toxic:
flammable and toxic, non-toxic or low-toxic and flammable, obviously it is
flammable, and Non-flammable and toxic harmful gas detectors are toxic, and the
last one is relatively complicated. If there is a person exposed to the poison,
the explosion can be measured if no one is exposed. For the explosion test,
select a flammable gas detection and alarm device, and for the poison test,
select a toxic gas detection and alarm device. Learn more about F2 Gas Detector
In
addition, there is the choice of the type of detection, whether it is a fixed
harmful gas detector or portable.
