Сьогодні, with the continuous enhancement of China's national strength and the increasing emphasis on environmental hygiene and detection, various types of gas detectors have been launched to detector hether the indicators of various gases are qualified. the gas detector can effectively detect the the concentration of a certain gas on site for 24 hours of continuous online monitoring and measurement of temperature and moisture, which plays an важлива роль в запобігання нещасні випадки. однак, generally speaking, the тип і концентрація of газ it detects are related, отже, detecting a certain gas has a certain range. Can gas detectors be used outside the concentration detection range?
Якщо the чотири in one gas detector conventionally detects горючі гази, водень сульфід, вуглець монооксид, and oxygen, the detection range is as follow:
1. Горючий газ (метан): between 10 percent LEL and 25 percent LEL, тобто 0.5 відсоток метан до 1.25 відсоток метан газ детектор воля тривога.
2. Водень сульфід газ: When it exceeds 10ppm, the gas detector will alarm.
3. Вуглець монооксид газ: The gas detector alarms when it exceeds 24ppm.
4. Oxygen: When it is below 18.0 percent , the gas detector will alarm.
For example, a горючий газ детектор with a detection range of 0-100} percent LEL may burn out the sensor if used to detect environments exceeding 100 percent LEL. the use of toxic gas detectors at high concentrations for extended periods of time can also cause damage to the sensors. So, if the gas detector emits an over limit signal during during use, the power switch should be негайно turned off щоб забезпечити безпеку з приладу.
