LASER Digital Circuit Logic Probe with Crocodile Clips

The LASER Digital Circuit Logic Probe is a professional-grade, hand-held pen-like test instrument, engineered for the precise analysis and troubleshooting of digital circuits. It provides clear, real-time indication of the logical states (Boolean 0 or 1) by detecting whether the measured voltage is above or below a pre-set threshold, illuminating the corresponding LED for immediate visual feedback. This device simplifies fault-finding by offering both visual and audio indications for steady logic levels and transient pulses, allowing for rapid diagnosis of signal integrity issues.

Conveniently powered directly from the circuit under test (5–15V DC), it eliminates the need for separate batteries or power supplies. The probe is supplied with extra-long 147cm leads terminated in robust crocodile clips, providing ample reach and a secure connection, making it particularly easy to use in expansive setups like around engine control units or within large equipment racks. Its high input impedance (1MΩ) ensures minimal circuit loading, preserving signal accuracy.
