When you evaluate the price against these protective features, the Kyoritsu KEW-4105A represents a cost-effective investment in high-quality test equipment.
Technical Features and Field Applications of the Kyoritsu KEW-4105A
The Kyoritsu KEW-4105A is more than just a standard meter; it is a sophisticated tool packed with features designed to streamline the measurement process. One of its most significant technical advantages is the ability to measure earth voltage in addition to resistance. This dual functionality allows technicians to perform comprehensive grounding checks without switching between different devices. Furthermore, the unit is designed to meet the stringent IEC61010-1 safety standard, providing an additional layer of assurance that the tester can withstand high-energy transients during operation.
In the field, ease of use is just as critical as accuracy. The Kyoritsu KEW-4105A features a large, easy-to-read LCD digital display, ensuring clear visibility in various lighting conditions. To accommodate different testing scenarios, the unit is supplied with test leads that facilitate a simplified two-wire measuring system. This design is particularly beneficial for quick checks where the unit can be conveniently hung from the neck, allowing the technician to use both hands for probe placement. Additionally, the simplified measurement probe structure combines an alligator clip and a test bar, enhancing versatility during on-site applications.
Advanced Safety and Measurement Capabilities
One of the primary concerns when performing earth resistance tests is the condition of the auxiliary earth spikes. The Kyoritsu KEW-4105A addresses this by incorporating an automatic warning system. This feature alerts the user immediately when the resistance of the auxiliary earth spikes exceeds the permissible limit. This is a critical function because high resistance in the auxiliary spikes can lead to inaccurate measurements, potentially masking dangerous grounding faults. By providing this real-time feedback, the device ensures that the testing setup is valid before the actual measurement begins.
Additionally, the Kyoritsu KEW-4105A is engineered for safety regarding the circuit under test. It utilizes a measuring current of just 2mA. This low current allows for earth resistance tests to be performed on circuits that contain earth leakage current breakers (ELCB/RCD) without causing them to trip. This is a vital feature for maintenance electricians who need to verify grounding integrity without disrupting the power supply to sensitive equipment or shutting down production lines. The combination of low current testing and automatic spike validation makes this model one of the safest and most efficient tools in its class.
Best Price Kyoritsu Earth Tester
When considering the purchase of the Kyoritsu KEW-4105A, it is important to evaluate its physical design and durability alongside its technical specifications. The instrument is small and lightweight, reducing operator fatigue during long testing sessions. Despite its compact size, it features a shock-resistant new case material that protects the internal electronics from accidental drops and impacts common in industrial environments. This rugged construction ensures that the device can handle the rough and tumble of daily field use, thereby extending its service life and protecting your investment.
To secure the best price on the Kyoritsu KEW-4105A, potential buyers should look for authorized distributors that offer genuine products backed by manufacturer support. The model is widely recognized for its reliability, and while pricing may vary slightly between suppliers, it is essential to ensure that the unit comes with all standard accessories, including the simplified measurement probes and test leads. For those comparing similar models, such as the Kyoritsu 4105DL, the KEW-4105A remains a top contender due to its balance of features, safety compliance, and competitive pricing. Ensuring you have the correct model for your specific testing requirements is the first step toward maintaining a safe and compliant electrical system.
