The following three points should be noted when using a portable gas detector.
Portable gas detection technology can be used for harmful gas detection, organic VOC gas detection, combustible gas detection, and single gas detection. The development of accurate warning and hidden danger detection technology is changing day by day, and its application in accident precursor inspection and elimination is becoming increasingly widespread. Its development direction is miniaturization and automation, in order to achieve long-term monitoring. The development of portable gas detectors enables leakage processes to be detected in the early stages. The occurrence of certain disasters is difficult to avoid. How to effectively suppress and monitor early warning, and how to make reasonable use of high-tech means to effectively control accidents that have already occurred, reducing casualties and property losses, are the practical problems that need to be addressed in key production safety technologies. By studying the physical and chemical properties of accidents in the early stages, gas detection and monitoring can effectively suppress potential disasters, enabling them to be controlled in advance while protecting personal safety. The key to the transformation from passive firefighting technology to a new generation of active prevention and control technology is centered around intelligent monitoring technology.
When using a portable gas detector, users should pay attention to the following three points:
1. Pay attention to the measurement range of the portable gas detector used:
Any gas detector has a fixed detection range, and only within this range can measurements be completed. Otherwise, the measured results will be much lower than the values in your environment. In addition, prolonged measurement beyond the range can cause damage to the sensor, resulting in inaccurate results even within the measurement range later on.
2. Pay attention to the service life of the sensors in the gas detector used:
Gas detectors have a limit on their service life, and portable gas detectors are no exception. Even if they are not used frequently, they can still experience aging. In general, among portable gas detectors, photoionization detectors have the longest lifespan of about four years; The service life of LEL sensors is second, and they can be used for more than three years; The lifespan of electrochemical specific gas sensors is relatively short, generally ranging from one to two years; The oxygen sensor can only be used for about a year.
So, before use, be sure to read the manual carefully and use the sensor within its expiration date. If it is found to be expired, it needs to be replaced immediately.
3. Regular calibration and testing of the detector are required:
