Perfectly crafted and ergonomically designed, the Kewtech KT300DL Digital Insulation/Continuity Tester is the perfect tool for meeting 18th edition testing requirements. With accuracy testing up to 1000V for insulation and up to 19.99kΩ for continuity, the KT300DL is a single function tester. After being updated from the Kewtech KT300, the Kewtech KT300DL now enables users to verify the presence of extraneous conductive parts by performing an SPD test and a 30k ohm continuity range. The KT300DL can be used hands-free by attaching it to a metal distribution board using a magnetic hanger. The Kewtech KT300DL offers a range of functions as standard and delivers precise and understandable test results on a digital display. Included are a buzzer mode, test lead null facility, audible tone feature, and hazard warning LED. Not only is the KT300DL a very dependable piece of equipment, but it is also a very dependable one. The Kewtech KT300DL is a lightweight, compact device with big buttons and an intuitive tactile dial interface. boasting an impressive 50-hour battery life and auto power off features that maintain working capacity for longer jobs. The KT300DL is rated at CAT IV 300V and CAT III 500V.
