The use of gas detectors and points to note
For those of us who deal with gases all day long, not only do we need to understand the characteristics of each gas we come into contact with, but we also need to understand the characteristics of the corresponding gas detection instruments.
Sulphur dioxide has a detection range of 0-200 with a resolution of 125 and a maximum concentration of 150;
Nitric oxide has a detection range of 0-250 with a resolution of 125 and a maximum concentration of 1000;
Ammonia The detection range is typically 0-50 with a resolution of 125, while the maximum concentration it can withstand is 200;
Carbon Monoxide has a detection range of 0-500 with a resolution of 125 and a maximum tolerable concentration of 1500;
Chlorine The detection range is typically 0-100 with a resolution of 100 and a maximum tolerable concentration of 500.
Hydrogen Sulfide The detection range is typically 0-100 with a resolution of 110 and a maximum tolerable concentration of 500;
The detection range of hydrogen cyanide is generally 0-100, the resolution is 110, and the highest concentration it can withstand is 100;
The use of gas detectors and points to note
In addition, we need to pay attention to the points are: First, pay attention to a variety of different sensors between the detection of interference: because between multiple instruments if the simultaneous work, and each kind of gas sensors are a specific kind of gas in order to be effective, but it can not be said to be safe, therefore, a few different gas detector at the same time work more or less will be some interference, in order to ensure the accuracy of the measurement results, we should Second, all kinds of sensors are limited life, here we have said before, should pay attention to the service life of the various gas sensors and timely replacement to ensure the accuracy of the measurement results; Third, pay attention to the measurable concentration range of the detector: the above mentioned a variety of gas detector can measure the concentration range, please try to measure the so-called range and so on, and only then, the instrument will measure more accurately. Only in this way, the instrument will measure more accurately, and annoying, if long time more than the measurable range of the gas detector overload, will certainly shorten the life of the detector.
