Earth resistance tester KEW4105DL + bag + reels 103943

Professional earthing measurements in difficult conditions

The KEW4105DL earth resistance tester is an advanced measuring tool enabling precise 2-wire and 3-wire method measurements across a wide range from 0.01 Ω to 2000 Ω.

The waterproof design with IP67 protection rating allows for measurements in conditions of increased dust and humidity.

Advanced measuring functions and safety

The device offers AC/DC earth voltage measurement up to 300V and effective noise reduction down to 25V rms, enabling accurate measurements even in locations with strong electromagnetic interference. A measurement frequency of approximately 825 Hz ensures reading stability across different soil types.

An LED for monitoring auxiliary earth connection status significantly simplifies the verification of connection correctness during measurements, eliminating the need for additional multimeter checks.

The device meets rigorous safety standards: PN-EN 61010-1, category CAT IV 100V/CAT III 150V/CAT II 300V, as well as IEC61557-1 and IEC61557-5 standards dedicated to measuring devices for protection against electric shock.

Construction and ergonomics

The meter features high ergonomic usability thanks to a rotary switch that allows for quick selection of operating modes without a complicated menu. A large backlit LCD display ensures readability of measurements even in poorly lit workspaces.

The compact design (121×59×188 mm) weighs only 690g with batteries. Power supplied by six LR6 (AA) alkaline batteries guarantees long-term operation without the need for frequent energy source replacements.

Regulatory compliance and certification

The device has full documentation of compliance with European standards: PN-EN60529 IP67 (protection against dust and water), IEC61326-1 (electromagnetic compatibility), and the RoHS EN50581 certificate confirming the absence of harmful substances.

The manufacturer recommends calibration of the meter every 12 months to ensure the maintenance of the declared measurement accuracy (±1.5% + digits for various ranges). The set includes measurement leads on reels (red - 20m, yellow - 10m, green - 5m) and a complete set of test probes for immediate start of work.
