The working principle of the resistance tester

When the battery rod is inserted into the suction nozzle, the suction of the suction nozzle ignites the electronic cigarette, and captures and maintains the instantaneous suction when it is ignited. The instantaneous suction force is compared with the suction force required by the standard. General standard value and lower limit. If it is lower than the lower limit, the screen will display low suction, and the unqualified red light will be on; if the instantaneous suction is between the lower limit and the upper limit, the screen will display qualified, and the qualified green light will be on; if the instantaneous suction is greater than the upper limit, the screen will display excessive suction, and the unqualified red light will be on Bright. And each sample can be automatically reset and cleared, so as to be used for the detection of draw resistance of electronic cigarettes.
