AUTOOL BT210 power circuit probe tester is specially used for the maintenance and detection of automobile electrical circuits. The measuring voltage range is 9-30V DC.

Four Modes Optional:
Voltage test: This upgrade circuit test light is a bidirectional voltage tester.
On-off test: can detect open circuit, path, virtual circuit and real circuit.
Positive and negative pole test: green light indicates positive polarity and red light indicates negative polarity.
Temperature test: the pointer is equipped with a temperature sensor to detect the temperature of the specified contact.

Wide Application : This professional automotive circuit tester light with 9-30V DC voltage testing range, widely and ideal for checking various vehicles, electrical circuits, automotive headlights, taillights, turn signal circuits, faulty sockets, fuse connections, also for testing other 9-30v DC wirings and circuits.

LED Digital Display & Auxiliary Lighting: Auto circuit light tester with LED digital display. When measuring, there is lighting LED beads will illuminate the measured circuit area, making night work more convenient than ever.

Overload Protection: When the voltage or current is overloaded, the circuit tester probe will activate the overload protection function to protect the equipment and personnel.

High quality 43.3 inch long wire offers more flexibility, lighter and more durable than normal cable wires, heat-insulation and oil resistance for daily use. Sharp stainless steel probe for piercing wires, also for hard to reach tight areas.
