Selection of Suitable Combustible Gas Detectors
Gas detectors are widely used in industries such as petrochemicals, environmental protection, gas, and coal mines. For various safety production scenarios and detection requirements, selecting the appropriate combustible gas detector is crucial for every personnel engaged in safety and hygiene work.
The first thing to consider is whether the combustible gas detector has stability. This is a factor that must be considered. The smaller the values of zero offset and full range offset, the better. All gas detectors will produce more or less interference reactions to gases other than oxygen, and the most common one is the electrochemical sensor for detecting hydrogen sulfide. Therefore, as daily users in home life, we must be familiar with the toxic gases that may exist in the home.
The second thing to consider is whether the combustible gas detector has easy identification. Numerical or pointer type gas detector. Generally speaking, numerical models have the advantages of easy readability and fewer false positives. Is the display area large enough with background lighting and large fonts for easy reading and understanding. Is the alarm sound loud enough to distinguish it from background noise. Generally applicable with an efficiency of 90dB (A) or above. Can the flashing alarm light be identified from various angles. Can the signal be continuously
displayed as the gas concentration changes, and the alarm will be stopped only after confirmation or countermeasures are taken.
The third thing to consider is whether the reliability of the combustible gas detector is good. The longer the lifespan of the sensor, the better. Generally speaking, the average lifespan of a combustible gas detector is 2-5 years, and the smaller the error value, the better. The precision and its precision will increase with the increase of service life, and the warranty period of the product is generally 2 years.
The fourth factor to consider is 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.
