Static detection pen, detection method and detection equipment for passive product

The invention provides an electrostatic detection pen, a detection method and detection equipment for a passive product, and the method comprises the steps: sensing electrostatic charges on the passive product through an electrostatic charge sensing assembly, and gathering the electrostatic charges into an electrostatic electric field; the electric field sensor adjusts the sensitivity and the signal frequency of the induction electrode to a stable state, and after the electric field sensor is connected with the electrostatic charge sensing assembly, the electrostatic charge in an electrostatic electric field is sensed and converted into a corresponding electrostatic charge value; the electrostatic charge sensing assembly comprises: a housing, in which a gathering area for gathering electrostatic charges is formed; the front end of the probe is located on the outer side of the shell, and after the probe is in direct contact with the passive product, electrostatic charges on the passive product are sensed; the
