Several Important Properties That Cannot Be Ignored for Gas Detectors
To enhance safety standards, gas detectors are being purchased across all industries nowadays. However, most buyers lack professional knowledge of the gas detection industry and struggle to select the right detector for their application scenarios. Below we elaborate on several indispensable characteristics of gas detectors that must not be overlooked:
① Stability Stability is a fundamental requirement and the top priority for selection. Check the values of zero drift and full-scale drift; the smaller the drift figures, the better.
② Portability Most inspections are carried out outdoors. On the premise of stable performance, portability is another critical factor. Ideal detectors should be lightweight and compact, easy and comfortable to wear, and simple to maintain and service.
③ Applicability Professional technicians shall identify and assess hazardous gases in confined space operation sites to verify whether the sensor
of the selected detector can meet actual working requirements.
④ Reliability A longer sensor service life is preferred. In general, the minimum service life of most sensors is 2 years, while catalytic combustible gas sensors last 2 to 5 years. Longer mean time between failures (MTBF) is desirable. Pay attention to accuracy and precision indicators; the lower the error margin, the higher the performance.
⑤ Protection Grade Confirm whether the explosion-proof rating matches the working environment, whether the product has passed official safety certification, and whether it is equipped with explosion-proof certificate and metrological verification certificate.
⑥ Readability & Visibility Check whether the display screen is large enough with clear fonts, whether the alarm volume is loud enough, and whether the warning indicator light can be clearly seen from all viewing angles.
