Four small skills in choosing a carbon monoxide gas alarm

The portable carbon monoxide gas detector has the advantages of small volume, stable performance, accurate measurement, simple operation and wide application in industry such as mines, if we want to carbon monoxide gas detector in use for better effect, Henan Outai electronic will remind everyone must pay attention to the following four points:
1. Pay attention to the measuring range of the concentration of the gas detector. The carbon monoxide detector has its fixed range of detection. The accurate measurement of the instrument can be ensured only if the measurement is completed within the range of its measurement.
2. Pay attention to regular calibration and detection. The toxic and harmful gas detector is the same as other analysis and detection instruments, which are measured by relative comparison method. Therefore, the calibration of the instrument at any time and the regular calibration of the instrument are essential to ensure the accuracy of the instrument.
3, pay attention to the detection interference between different kinds of sensors. Generally speaking, each gas detector sensor corresponds to a specific detection gas. Therefore, when selecting a gas sensor, we should know the detection interference of other gases to the sensor as far as possible.
4, pay attention to the life of all kinds of sensors. Generally speaking, the portable instrument, the LEL sensor can live for about three years; electrochemical sensor life depends on the electrolyte dries up, so if not used for a long time, the sealing in low temperature environment can prolong the service life of a certain. Because of the relatively large volume of the fixed instrument, the life of the sensor is longer. The lifetime of the photoionization detector is four years or longer. The lifetime of the electrochemical specific gas sensor is generally one to two years. The lifetime of the sensor is about a year.
In addition to carbon monoxide alarm, sales of our company also specializing in the production of gas detector, gas alarm, gas leak detector, advanced technology, the company adhere to the technical innovation, continuous innovation, adhere to the development, and constantly improve the enterprise economic benefits and social benefits, to become the most trusted user gas alarm instrument suppliers.
