ポータブル ガス 検出 技術 缶 使用 有害 ガス 検出, 有機 VOC ガス 検出, 可燃性 ガス 検出, and single gas detection. 正確 警告 の 隠された 危険 検出 技術 is developing with each passing day, and its application in the inspection and elimination of accident precursors is becoming more and more extensive. its development direction is miniaturization and automation, in order to achieve 長期 モニタリング。
ポータブル ガス 検出器 are widely used in industrial safety monitoring, indoor air quality detection, hazardous substance detection, and environmental protection monitoring. Targeting the key links in the process of disaster breeding, occurrence, and development and destroying its chain development chain is an important part of the safety accident prevention and control technical system.
Pay attention to the measuring range of the portable gas detector used:
Pay attention to the service life of the sensor in the gas detector used:
ガス 検出器 have a limited service life, and portable gas detectors are no exception. Even if they are not used fquently, they will still experience aging. generally speaking, among portable gas detectors, the photoionization detector has the longest lifespan, which is about four years; the LEL sensor has the second longest lifespan, which can be used for more than three years; the electrochemical specific gas sensor has A 比較的 短い 寿命. , 通常 1 TO TWO YEARS; The Oxygen Sensor Can only BE USED FOR ABOUT One YEAR。
したがって、, be sure to read the instructions before use and use the sensor within its validity period. If it is found to be expired, it needs to be replaced immediately.
検出器 ニーズ に be calibrated and tested 頻繁に:
携帯用 gas detectors generally use a relative comparison method for measurement. The measurement method is as follows:
1. First calibrate the instrument with a standard concentration of gas and a zero gas, and obtain the standard curve and store it in the instrument;
2. 比較 the electrical signal of the standard concentration with the electrical signal generated by the gas concentration to be measured, and obtain the accurate gas concentration value after calculation。
