How to pick the best gas detector for combustible
Gas detectors are widely used in petrochemical, environmental protection, gas, coal mine and other industries. For various safety production occasions and detection requirements, it is very important to choose a suitable combustible gas detector for everyone engaged in safety and health work .
The first depends on whether the combustible gas detector is stable. 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 to gases other than oxygen. The most common occurrence is detection The electrochemical sensor of hydrogen sulfide, so as daily users in home life, we must be familiar with the toxic gases that may exist in the home.
The second depends on whether the combustible gas detector is easy to identify. Numeric 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.
The third depends on whether the reliability of the combustible gas detector is good. The longer the life of the sensor, the better. Generally speaking, the average life of a flammable 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 2 years.
The fourth depends on whether the combustible gas detector is convenient to use. A good combustible gas detector has the following characteristics: light weight, small size, easy and comfortable to wear, and easy maintenance.
