KYORITSU EARTH TESTER KEW 4105A

A Compact and Reliable Earth Tester

In the demanding world of electrical installation and maintenance, a professional’s toolkit is their most valuable asset. While sophisticated, all-in-one devices have their place, there is an enduring need for simple, reliable, and highly effective tools designed for a single purpose. This earth tester embodies that philosophy, offering an elegant solution to the fundamental task of measuring earth resistance. Its design prioritizes ease of use and durability, making it an ideal companion for day-to-day work. The tester’s small and lightweight form factor, coupled with a new shock-resistant case material, ensures it can withstand the bumps and drops of a typical job site without compromising its functionality. For a professional, this means less time worrying about equipment and more time focused on the task at hand. The included soft case further enhances its portability, allowing it to be easily carried and deployed wherever it is needed. This combination of robust physical design and straightforward operation makes it a go-to choice for any professional who values efficiency and reliability in their instruments.

Simple Readings from Advanced Measurement Circuitry

The primary function of any earth tester is to provide accurate resistance measurements, and this instrument achieves this with a blend of advanced technology and intuitive design. The device’s latest circuit design is a testament to its engineering excellence. It is specifically built to operate with minimal influence from earth voltage and the resistance of auxiliary earth spikes, which are common sources of error in less sophisticated testers. This ensures that the professional can rely on the reading, even in noisy or less-than-ideal grounding conditions. The tester supports both 3-Pole and 2-Pole Earth Resistance measurement, providing the versatility needed for a variety of applications, from precision testing of an earth electrode to quick continuity checks. What truly sets this tester apart in its class is the inclusion of a large, easy-to-read LCD digital display. This provides clear, unambiguous readings that are perfect for on-the-spot assessments and official reporting. With three distinct ranges of 0-19.99Ω, 0-199.9Ω, and 0-1999Ω, the professional can cover a wide spectrum of resistance values with confidence, knowing the digital display provides an accurate and precise value.

Low Current Prevents Tripping RCDs

In modern electrical systems, Earth Leakage Current Breakers (ELCBs) and Residual Current Devices (RCDs) are ubiquitous, serving as vital safeguards against electrical shock. However, these sensitive devices can pose a challenge for traditional earth testers, as the test current can be high enough to cause them to trip, leading to power outages and frustrating delays. This instrument ingeniously solves this problem with a low 2mA measuring current. This small but significant innovation permits earth resistance tests without tripping earth leakage current breakers in the circuit under test. For professionals working on a live system, this feature is invaluable. It means they can perform a critical safety check without disrupting the power supply to the building, saving both time and the hassle of resetting breakers. This efficiency is a core advantage that not only improves the professional’s workflow but also minimizes disruption for the end-user. The ability to conduct these essential tests non-disruptively is a key differentiator that makes this tool a must-have for modern electrical work.

Built Tough for Field Reliability

A professional’s tool must be a model of durability, capable of withstanding the challenging environments of daily work. This earth tester’s design is a perfect embodiment of this principle. It is dust and drip proof (designed to IEC 60529 IP54), a certification that signifies its protection against a limited ingress of dust and water splashes from any direction. This makes it a reliable choice for working outdoors in light rain or in dusty attics and crawl spaces. The tester’s physical construction also stands out. The use of a new shock-resistant case material ensures that the device can survive accidental drops or impacts that are common on job sites. This durability is coupled with exceptional portability. The device is small, with dimensions of 105(L) × 158(W) × 70(D) mm, and incredibly lightweight at only 550g (including batteries and case lid). This compact size and light weight, combined with the included soft carrying case and shoulder strap, mean that the tester is easy to transport, easy to handle, and ready to go wherever the job takes you.

Upholding the Highest Safety Standards

For any electrical professional, safety is the top priority, and their tools must reflect this commitment. This earth tester is designed to meet IEC 61010-1 safety standard, a definitive benchmark for electrical testing equipment. Its specific rating of CAT III 300 V Pollution degree 2 provides professionals with the confidence to use the device safely on fixed installations, such as distribution boards and wiring. The instrument also features robust overload protection, safeguarding the internal circuitry from accidental exposure to higher voltages. The Earth resistance function is protected up to 280V AC for 10 seconds, and the Earth voltage function is protected up to 300V AC for 1 minute. These protections are crucial for mitigating risks associated with accidental contact with energized circuits. In addition to measuring resistance, the device is also capable of measuring earth voltage (0 to 200V AC), which is a valuable diagnostic feature. A professional can use this function to check for the presence of stray voltages in the earth system, which can be an early indicator of a fault. This combination of strict adherence to international safety standards, integrated overload protection, and an earth voltage measurement capability provides a comprehensive safety package that professionals can trust.

A Versatile Tool for Everyday Tasks

The straightforward yet robust design of this earth tester makes it a highly versatile and indispensable tool for a wide range of professional applications. For residential electricians, the device is perfect for performing quick earth resistance tests during new installations or when troubleshooting existing wiring issues. Its low 2mA test current is a major benefit in these settings, as it allows for testing without tripping the RCDs that are common in modern homes. Facilities managers and maintenance technicians can use the tester for periodic safety checks on building earth systems, ensuring compliance and the ongoing safety of the occupants. The large digital display and lightweight design make it ideal for quick checks in hard-to-reach areas. HVAC technicians can use the device to verify the earth continuity of their equipment, which is critical for both safety and proper operation. Even small-scale solar installers can use this tester to perform basic earth resistance checks for the grounding of their panel arrays. The product’s blend of simplicity, durability, and a unique anti-trip function makes it the perfect tool for a variety of everyday tasks where a reliable and non-disruptive earth test is required.
