KYORITSU 3007A Digital Insulation / Continuity Tester (Made In THAILAND)

Description

KYORITSU 3007A Digital Insulation / Continuity Tester (Made In THAILAND) The KYORITSU 3007A Digital Insulation / Continuity Tester (Made In THAILAND) is a handheld, microprocessor-controlled digital tester designed to measure both insulation resistance and continuity in electrical circuits. Encased in a robust, dust- and drip-proof (IP54) housing, it delivers test voltages of 250 V, 500 V, or 1000 V DC for insulation checks and up to 12 V DC for continuity tests. Its dual-integration circuitry ensures stable readings across a wide temperature and humidity range, while built-in safety features comply with IEC 61010-1 (CAT III 300 V) and related standards for low-voltage distribution systems. Equipped with a 30-point bar graph, live-circuit warning buzzer, AUTO NULL, and auto-discharge, the 3007A simplifies complex testing routines. The TRAC-LOK mode (exclusive to the 3007A) locks output once a stable reading is detected, conserving battery life. A back-lighted LCD facilitates work in dim environments, and an auto power-off prevents unintended battery drain. Ideal for maintenance and troubleshooting tasks, this tester handles everything from cable jacket insulation checks to panel continuity examinations. Lightweight at under 1 kg (including batteries) and fitted with a neck strap, it frees both hands for probe placement. Its rapid sample rate (0.5–2.5 readings/sec) and rugged design make it a reliable companion for electricians, facilities engineers, and safety inspectors. Features: Microprocessor‐controlled insulation and continuity measurements. Compliance with IEC 61010-1, IEC 61010-2-030 (CAT III 300 V), and IEC 61557 series. Back-lit LCD display for work in low-light conditions (3007A only). 30-segment bar graph for quick trend indication. Ergonomic strap belt for hands-free operation. Live-circuit warning indicator and audible buzzer. AUTO DISCHARGE function to safely bleed off stored charge. AUTO POWER OFF after approximately 10 minutes of inactivity. TRAC-LOK mode to lock the test voltage once a stable reading is detected (3007A only).
