Three Key Points for Using Portable Gas Detectors
Portable gas detection technology can be applied to hazardous gas detection, organic VOC gas detection, combustible gas detection and single gas detection, and deliver accurate early warnings against potential hazards. This detection technology is evolving rapidly and is increasingly widely adopted for pre-incident inspection and hazard elimination. It is developing toward miniaturization and automation to realize long-term monitoring. Thanks to the advancement of portable gas detectors, gas leakage can be identified at the initial stage.
Certain disasters cannot be completely avoided. The core practical issues to be addressed by key production safety technologies include effective suppression, monitoring and early warning, as well as rational application of high-tech tools to control ongoing accidents and reduce casualties and property losses. By studying the physical and chemical properties of incidents in their early phase, gas monitoring enables pre-disaster suppression to contain potential accidents in advance and protect personal safety. Intelligent monitoring technology serves as the core driving force for the transition from passive fire fighting and rescue technologies to a new generation of active prevention and control technologies.
Users shall pay attention to the following three points when operating portable gas detectors:
① Mind the measuring range of the portable gas detector in use Every gas detector has a fixed detection range. Reliable measurement can only be completed within this range; otherwise, the reading will be far lower than the actual gas concentration on site. In addition, long-term measurement beyond the specified range will damage the sensor, leading to inaccurate readings even within the normal measurement range afterwards.
② Pay attention to the service life of the sensor equipped in the gas detector All gas detectors have a limited service life, and portable models are no exception. Sensors will age even if the instrument is not used frequently. Generally speaking, photoionization detectors have the longest service life of approximately four years; LEL sensors rank second with a usable life of more than three years; dedicated electrochemical gas sensors have a relatively shorter lifespan of one to two years; oxygen sensors can only work for around one year.
Therefore, the user manual must be read carefully before use, and the detector shall be operated within the valid period of the sensor. The sensor needs immediate replacement once it expires.
③ Conduct regular calibration and testing for the detector
