VEVOR Automotive Circuit Tester, 8 - 35 DCV Power Circuit Probe Tester with TFT Color Display and Lighting, Automotive Power Tester Probe with 19.7 ft / 6 m Cable, 2-in-1 Electrical Detector Finder

Auto Probe Tester With -110V to +110V Wide Voltage Detection for Vehicles

The auto probe tester can operate over a -110V to +110V DC voltage range, covering low- and high-voltage circuits found in modern vehicles. It is designed to work with standard vehicle batteries via an 8-35V DC power supply. The device operates using power from the vehicle's battery and does not require any additional external power sources. It is compatible with gasoline, hybrid, and electric vehicles, as well as the electrical components found in most modern vehicles. 

Technicians can instantly recognize deviations in voltage, current fluctuations, and waveform anomalies. The probe tester prevents incorrect diagnosis and is an important tool for experts performing maintenance, allowing them to check the electrical condition of large trucks, compact cars, and hybrid vehicles. The ability to scan a wide range of voltages makes this device essential for its intended application.

1.77-Inch TFT Color Display With Real-Time Waveform and Numeric Readings

Built around a 1.77-inch TFT color display, the probe tester offers real-time waveform visualization, numeric reading, and signal analysis for super-accurate circuit diagnosis. The high-contrast display even makes complex signals easier to read, with reduced susceptibility to testing errors.

Equipped with seven single-purpose function buttons, users can efficiently complete tests for AC/DC voltage, frequency, duty cycle, resistance, diode operation, and fuel injector performance testing. The probe tester consolidates multiple functions into a single tool, minimizing the need for additional equipment and speeding up processes in busy professional automotive workshops.

Fuel Injector Frequency and Duty Cycle Testing for Precise Engine Diagnostics

The auto probe tester also checks the fuel injector pulses for frequency and stability, taking into account the engine's operating cycle, to ensure the fuel flow rate required for efficient engine operation. This tester helps identify fuel injector faults through irregular frequency and duty cycle readings.

Technicians can analyze injector operation in real time and identify discrepancies that can then be corrected with precision, supporting optimal fuel efficiency and responsive engine performance. This capability ensures that the auto probe tester has become a vital tool for fuel system analysis and helps prolong engine life by enabling efficient maintenance.

19.7 ft Long Cable With Universal Connectors For Extended Testing

This tester is supplied with a 19.7 ft cable. This helps cover a longer span, especially on large engines, trucks, or vehicle chassis. This tool not only saves time and effort but also increases convenience.

The universal connectors ensure it can be connected to most vehicle electrical systems and accessories. The long cable ensures effective diagnostics at car garages, auto service centers, or on the roadside. The probe tester enhances convenience, streamlines workflows, and reduces time spent examining and repairing electrical systems, thereby boosting productivity.

Multi-Function Tester with Polarity, Resistance, Continuity, and Duty Cycle

This tester supports polarity testing, resistance measurement, continuity verification, frequency analysis, duty cycle monitoring, diode testing, and component activation, providing a comprehensive electrical evaluation in a single compact device. This allows comprehensive testing without relying on multiple separate tools.

Technicians can directly actuate relays, solenoids, and actuators to verify their proper operation without disassembly. The probe tester minimizes the number of tools a technician carries, increases accuracy, and streamlines repair processes in a busy professional workshop, making it an indispensable tool for today's vehicle maintenance.

Built-In LED Flashlight for Accurate Diagnostics in Dark Engine Compartments

This tester includes an LED flashlight. This enables technicians to perform diagnostics clearly, even in low-light conditions. It also helps reduce the risk of misdiagnosis. Along with its user-friendly interface, the flashlight enhances its usability in the workshop and on the road. The auto-probe tester enables technicians to perform accurate diagnostics in environments with limited lighting.

Compact Auto Probe Tester With 2.43 lbs ABS Shell and Bright Orange Finish

Constructed from rugged ABS material, the auto probe tester weighs 2.43 lbs (1.10 kg) and measures 8.15 × 2.17 × 1.46 inches (207 × 55 × 37 mm) for easy carrying and storage. Designed compactly and in bright orange, this makes handling, storing in tool bags, or transporting in vehicle trunks easy during mobile service calls.

Heavy-duty ABS shell resists damage to internal components from shock, drops, and other workshop hazards, while ergonomic contours provide sure control during extended diagnostic sessions. The durable probe tester strikes the perfect balance between durability, light weight, and comfort for the professional technician who is often on the move between workshops and field inspections.
