What criteria are there for choosing a gas detector?
Applicability: Real estate professionals should conduct on-site identification and evaluation of harmful gases in the limited space where the home is located to determine whether the installed toxic gas detector sensor meets the needs of use.
Easy to identify; numerical or pointer gas detector. Generally speaking, the numerical type has the advantages of easy readability and less misjudgment. Is the display area large enough with backlighting and large fonts for easy reading and comprehension. Whether the siren is loud enough to be distinguished from the background noise. Generally, the efficiency above 90dB(A) is applicable. Whether the warning flashing light can be recognized from various angles. Can the signal be displayed continuously with the change of the measured gas concentration, and the alarm will be stopped after confirmation or countermeasures are taken.
Stability; this is a factor that must be considered. The smaller the value of zero offset and full amplitude offset, the better. All gas detectors will produce more or less interference reactions except for gases other than oxygen, most often The most important thing is the electrochemical sensor for detecting hydrogen sulfide, so as daily users in home life, we must be familiar with the toxic gases that may exist in the home.
Reliability: The longer the life of the sensor, the better. Generally speaking, the average life of the combustible gas detector is 2-5 years, and the smaller the error value, the better. The accuracy and its precision will increase with the increase of the service life, and the warranty period of the product is generally 1 year.
Convenience; now we are all working outside, convenience is also a factor that has to be emphasized under the premise of stability: light weight, small size, easy and comfortable to wear, and easy maintenance.
