The gas detector is mainly used to detect the concentration of gas leakage in the space, and its use is of great significance to environmental engineering. Only by making good use of the gas detector can the accuracy of the detection data be achieved, and then help people make correct judgments.
The main precautions for using the gas detector are as follows:
1. It is necessary to carefully read the instruction manual, install the instruction manual to operate, and do not press it at will without understanding the meaning of the operation menu, and modify the internal data at will. When you encounter the required function and don't know how to operate it, please pay attention to the operation process of this function in the manual.
2. Pay attention to whether the measuring range of the machine is suitable. Do not use it for a long time with high-concentration gas exceeding the measuring range, otherwise it will cause high-concentration gas poisoning. Once the sensor is poisoned by high-concentration gas, there will be no response to measurement again. , Or the zero drift is large.
3. When using the gas detector, you must not discard it or shake it vigorously, because the internal sensor of the detector contains electrolytic liquid substances. Vigorous shaking will cause the electrolyte to shake and cause the data in the detection process to be inaccurate or cause the zero point to drift too much. , So avoid vigorous shaking or installing on vibrating equipment.
4. The gas detector is a high-precision instrument, so try to avoid electromagnetic interference areas that affect the stability of the instrument during use. Many gas detectors on the market have failed to pass the electromagnetic interference test standards. Therefore, it is necessary to pay attention. Of course, even the instruments that have passed the electromagnetic interference test should avoid application testing under such conditions as much as possible.
