Operation and Key Precautions of Gas Detectors
Our friends who deal with gases all day long not only need to understand the characteristics of each gas we come into contact with, but also need to know the characteristics of the corresponding gas detection instruments.
The detection range of sulfur dioxide is generally 0-200, with a resolution of 125, and its maximum allowable concentration is 150;
The detection range of nitric oxide is generally 0-250, with a resolution of 125, and its maximum allowable concentration is 1000;
The detection range of ammonia is generally 0-50, with a resolution of 125, and its maximum allowable concentration is 200;
The detection range of carbon monoxide is generally 0-500, with a resolution of 125, and its maximum allowable concentration is 1500;
The detection range of chlorine gas is generally 0-100, with a resolution of 100, and its maximum allowable concentration is 500.
The detection range of hydrogen sulfide is generally 0-100, with a resolution of 110, and its maximum allowable concentration is 500;
The detection range of hydrogen cyanide is generally 0-100, with a resolution of 110, and its maximum allowable concentration is 100;
The use and precautions of gas detectors
In addition, we need to pay attention to the following points: firstly, be aware of the detection interference between various sensors: because if multiple instruments work simultaneously, each gas sensor needs a specific gas to be effective, but it cannot be said to be . Therefore, if several different gas detectors work simultaneously, there will be some interference to some extent. In order to ensure the accuracy of measurement results, we should try to avoid interference as much as possible; 2, The lifespan of various types of sensors is limited. As we have mentioned before, we should pay attention to the lifespan of various gas sensors and replace them in a timely manner to ensure the accuracy of measurement results; 3, Pay attention to the measurable concentration range of the detector: As mentioned above, various gas detectors can measure concentrations within this range. Please try to measure within this so-called range as much as possible. Only in this way can the instrument measure more accurately. However, if the gas detector is overloaded for a long time beyond the measurable range, it will inevitably shorten the life of the detector.
