Four factors that can't be ignored when choosing a carbon monoxide detector

The gas detector is small in size and easy to operate. However, in order to make the gas detector perform better during use, attention should be paid to the following four points in use:

First, pay attention to the life of various types of sensors: Generally speaking, in portable instruments, the life of LEL sensors can generally be used for about three years; the life of photoionization detectors is four years or longer; Electrochemical specific gas sensors The life expectancy is generally between one year and two years; the life of a carbon monoxide detector sensor is approximately one year. The life of the electrochemical sensor depends on the dryness of the electrolyte, so if it is not used for a long time, sealing it in a lower temperature environment can prolong the service life. Because of the relatively large size of the stationary instrument, the life of the sensor is longer.

Second, pay attention to the regular calibration and testing: toxic and harmful gas detectors are the same as other analytical testing instruments. Therefore, zero calibration of the instrument at any time, and regular calibration of the instrument is an indispensable task to ensure accurate measurement of the instrument.

Third, pay attention to the measurement range of the measuring instrument: The carbon monoxide detector has its fixed detection range. Only when the measurement is completed within its measurement range can the instrument be accurately measured.

Fourth, pay attention to the detection interference between various sensors: Generally speaking, each gas detector sensor corresponds to a specific detection gas. Therefore, when selecting a gas sensor, it should be understood as much as possible about other gases. The sensor detects interference.

Wood Chipper Machine

The High Capacity Wood Chipper machine is the special equipment of making high quality wood chips for flakeboard, the base of production and export of fiberboard, and papermaking and wood chips plant.


It is widely used in stock workshop section of industrial manufacture. For example, the flakeboard, fire board, building board, straw power plant.The raw material is small diameter wood,timber harvesting, processing residues (such as branches, twigs, planks, logs cores,waste veneer, etc), it can also be used for other materials (such as sugar cane, reed,bamboo,etc.).
