Description

Componented by the oxygen sensor equipment (oxygen electrode) and the second instrument, and so on, with the Light firm, and the desirability to the characteristics. LCD, a 9 V DC power supply. Access a national patent, patent No. ********5. ZJ*3CY measuring oxygen**2C on the following occasions for the gas in the determination of oxygen content is particularly applicable. 1, industrial and mining enterprises on the environment, the cabin, trenches, chemicals, fertilizers, industrial gases in the determination of oxygen content to avoid the production process as peracetic system and the explosion occurred, and to prevent maintenance personnel in the hypoxic environment asphyxia accident occurred is very effective. 2, the internal combustion engine exhaust oxygen content and oxygen content in the flue gas detection in order to achieve reasonable control of combustion and fuel-efficient. 3, the food, fruit, vegetables, tobacco, herbs, dried fruits, oxygen content in such a gas storage . 4, the medical cause of the breathing machine, anesthesia machine, the hyperbaric oxygen chamber infant incubators, as well as aerospace, diving operations oxygen content analysis. 5, secondary schools, institutions of higher learning, the Faculty of Medicine of physical, chemical, biological, and other aspects of experimental indispensable laboratory equipment. 6, adapt to the meteorological department, pharmaceutical injections quality of the oxygen content. Technical performance 1, range ****0% ***5% **5% 2, accuracy: ± 0.*5% (oxygen content of less than 5%) ± 0.3% (5% **5%), ± 3% (over *0%).
