Kyoritsu 3551 Digital Insulation Resistance Tester, 6 ranges

Description

The Kyoritsu 3551 is a six-range digital insulation and continuity tester known for its extremely fast measurement speed and high-level safety features. It is designed for electrical professionals for quick and accurate assessment of insulation resistance and continuity in a variety of applications.

Key Features

• Extremely fast measurements: The device can perform insulation resistance measurements in as little as 0.5 seconds, significantly reducing testing time.
• Multiple test voltages: It features six selectable test voltages—50V, 100V, 125V, 250V, 500V, and 1000V—providing versatility for different testing requirements.
• Integrated functions: The Kyoritsu 3551 combines three key functions in one unit: insulation resistance testing, continuity testing, and voltage measurement.
• Enhanced safety: It offers full protection against accidental connection to a live circuit. An auto-discharge function is included to safely discharge any capacitive charge in the circuit after an insulation test.
• Automatic voltage detection: The tester can automatically detect whether the measured voltage is AC or DC.Clear,
• Backlit display: A large, digital LCD with a backlight makes readings easy to see, even in dark environments.
• Continuity testing: The continuity function includes a 0 \(\Omega \) adjustment to compensate for the resistance of test leads, ensuring more accurate low-resistance measurements.
• Status indicator: The insulation status indicator provides a quick pass/fail judgment with LCD backlight color that changes based on the test result.
• Compact and robust: With an IP40 rating (IP64 for the 3552 and 3552BT models when the lid is closed) and a durable design, the device is built to withstand field use.
