Several Non-Negligible Characteristics of Gas Detectors
To enhance safety, gas detectors are currently purchased across all industries. However, ordinary buyers lack familiarity with the gas detection industry and do not know how to select a detector suitable for their working conditions. Below we introduce several non-negligible characteristics of gas detectors:
① Stability Stability is essential and our primary consideration. Check the values of zero drift and full-scale drift; the smaller the values, the better.
② Portability Field operations are common nowadays. On the premise of guaranteed stability, portability is also a vital factor. The detector should be lightweight and compact, easy and comfortable to wear, and simple to maintain.
③ Applicability Technicians shall identify and assess hazardous gases at confined-space work sites to verify whether the sensor of the selected detector meets operational requirements.
④ Reliability A longer sensor service life is preferred. Generally, the minimum service life of most sensors is 2 years, while combustible gas sensors last 2 to 5 years. A longer mean time between failures (MTBF) is desirable. Check the accuracy and precision; the smaller the error, the better.
⑤ Protection Requirements Verify whether the explosion-proof rating is applicable to the workplace, whether the product has passed safety certification, and whether explosion-proof certification or metrological certification is available.
⑥ Visibility & Identifiability Check whether the display area is large enough with clear fonts, whether the alarm sound is loud enough, and whether the alarm flashing light can be recognized from all angles.
