Sensor type and application conditions , you should follow the recommended calibration method

The method of calibration . Taking into account all the factors , such as sensor type and application conditions , you should follow the recommended calibration method : According to the operator's judgment , gas sensors surrounding gas is fresh , there is no abnormalcondition exists , then, the instrument indication near zero ( reading ) , zero setting process can be skipped. When in doubt , use a plastic bag aroundCamshaft Position Sensor to get some considered to be " fresh " air. This is a very quick and easy process . This method for the difference between true and false alarm warning is very effective . There is an advantage that the compressed air , the gas in the bottle is easy to control and easy to carry . The device is easy and convenient to get air . Such a small amount of air in the meaning of hydrogen and nitrogen , carbon monoxide , carbon dioxide and some other interfering gases . However , this gas is characterized by low humidity , the solution used in the sampling system with activated carbon filters are used to filter out unwanted wet gas in the gas and water vapor. After this process , we can use the gas for various types Car Temperature Sensor calibration . However, it should be noted that carbon monoxide gas and not through a filter with activated carbon and filtered . Therefore, the rule states: cylinders of carbon monoxide gas with the surrounding environment must be the same content . In addition , the use of soda ash filter can filter out carbon monoxide. Since the sampling system using the soda ash line filter can filter out although an oxygen gas is usually very pure man , but it can not be used for solid-state Engine Water Temperature Sensor and
photoionization detectors, because such sensors require the gas contained in the sampling some water vapor. A simple way to solve this problem is to use the sampling system pipeline damp tissue paper . Its role is to make the wet stream sample , the sensor has sufficient water vapor. Another option of using NAFION tube
