Description
Earth 4 Sure Monitor is a compact, UK‑manufactured ESD tester designed for reliable, continuous wrist‑strap and Earth monitoring at any EPA workstation.
The Earth 4 Sure Wrist Strap & Earth Tester is a compact, under‑bench monitoring unit that ensures operators remain safely grounded at all times. Designed for use within an Electrostatic Protected Area (EPA), the tester quickly checks to see whether an anti-static wrist strap is working correctly while also simultaneously confirming the Earth is present working in collaboration with the IEC 61340-5-1 specifications.
Manufactured in the UK and assembled at Bondline, the E4Sure offers dependable performance, simple operation, and long‑term durability for electronics manufacturing, assembly, inspection, and repair environments. E4Sure can be powered by a 9-volt PP3 alkaline battery. All ESD test equipment are manufactured to the very highest quality allowing qualification to council directives 89/336/EEC.
