What are the precautions when purchasing a carbon monoxide gas alarm
Due to the compact size of the carbon monoxide CO gas detector and the internal micro processing sensor being a high-precision sensor component, the user-friendly design is easy to operate. However, in order to ensure better performance of the carbon monoxide CO gas detector during use, Ousenjie Technology reminds everyone to pay attention to the following four important precautions:
1、 Pay attention to regular calibration and detection: Toxic and harmful gas detectors, like other analytical and detection instruments, are measured using relatively comparative methods. Therefore, zero calibration of the instrument at any time and frequent calibration of the instrument are essential tasks to ensure accurate measurement.
2、 Pay attention to the lifespan of various sensors: Generally speaking, in portable instruments, the lifespan of LEL sensors can generally be used for about three years; The lifespan of an electrochemical sensor depends on the drying of the electrolyte, so if it is not used for a long time, sealing it in a lower temperature environment can extend its service life to a certain extent. Fixed instruments have a longer lifespan due to their relatively large volume. The lifespan of the photoionization detector is four years or more; The lifespan of electrochemical specific gas sensors is generally one to two years; The lifespan of the carbon monoxide detector sensor is approximately one year.
3、 Pay attention to the detection interference between different sensors: generally, each gas detector sensor corresponds to a specific detection gas, so when selecting a gas sensor, you should try to understand the detection interference of other gases on the sensor.
4、 When choosing a carbon monoxide CO gas detector, everyone should pay attention to four key factors. Pay attention to the concentration measurement range of the detection instrument: The carbon monoxide detector has a fixed detection range. Only by completing the measurement within its measurement range can the instrument ensure accurate measurement.
