1. Pay attention to detection interference between various sensors

3. Pay attention to the lifespan of various sensors

4. Pay attention to the concentration measurement range of the detection instrument:
Various types of toxic and harmful gas detectors have their own fixed detection ranges. Only by completing measurements within its measurement range can the instrument ensure accurate measurement. Measuring beyond the measurement range for a long time may cause damage to the sensor. For example, if an LEL detector is accidentally used in an environment exceeding 100% LEL, the sensor may be completely burned out. Toxic gas detectors can also be damaged if they are used at higher concentrations for a long time. Therefore, if a fixed instrument sends out an over-limit signal during use, the measurement circuit must be shut down immediately to ensure the safety of the sensor.

Currently, the detectors available to us include fixed/portable, diffusion/pump type, single gas/multi-gas, inorganic gas/organic gas and other combinations. Only by choosing the appropriate gas detection instrument can we truly achieve twice the result with half the effort and prevent problems before they occur.
