What are the types of test pens?
1. According to the high and low voltage measurement
High voltage testing pen: used for projects with a voltage of 10kV and above, as a daily testing tool for electricians;
Low voltage measuring pen: used for detecting charged objects in projects with a line voltage of 500V or below.
Weak current tester: used for testing electronic products, generally with a testing voltage of 6v-24V. For ease of use, the tail of the tester often has a lead wire with a clamp.
2. Classified by contact method
Contact type test pen: a detection tool that obtains electrical signals by contacting charged objects. Usually in the form of a straight screwdriver, it can also be used as a test pen and a straight screwdriver; Pen style, displaying measurement data directly on the LCD window.
Inductive test pen: using inductive testing, without physical contact, it can check the voltage on control lines, conductors, and sockets or check the position of open circuits along the wires. It can greatly ensure the personal safety of testing personnel.
3. Neon tube measuring pen
Neon tube measuring pen, also known as electric pen, is used to check whether the metal casing of wires, electrical appliances, and electrical equipment is live. This type of electric pen is divided into two forms: pen type and screwdriver type.
4. Digital measuring pen
Digital display measuring pen, also known as induction measuring pen. This type of electric pen can not only test whether an object is charged, but also display a rough voltage range. Some digital measuring probes can detect the location of broken insulated wires.
