Combo Tester X3 for Wrist Strap and Footwear, with stand - Desco 19271

Verifying the grounding of every operator at the EPA entrance each day needs a fast, repeatable test. The Desco Combo Tester X3 checks the wrist strap and the left and right foot in three independent, simultaneous measurements and returns a result in less than 3 seconds. This version is supplied with stand.

Key benefits

• Three tests in one step: wrist strap, left foot and right foot are tested at the same time, and the split foot plate flags a failed foot grounder individually.
• 30 V test signal for accurate results that do not depend on humidity.
• Solid-state touch switch with no moving parts keeps the tester accurate and extends its service life.
• Relay terminal for electronic door locks or turnstiles, so only operators who pass can enter the EPA.
• Green LEDs for pass, red and yellow LEDs plus audible alarm for fail, test limits selectable via DIP switches.
• NIST traceable calibration from the factory, limits can be checked in place with the Desco Limit Comparator.

Applications

Personnel grounding checks at EPA entrances in electronics manufacturing, labs and service areas. It verifies single-wire and dual-wire wrist straps, heel and foot grounders, ESD shoes and groundable static control garment systems (Rtg below 3.5 x 10⁷ ohms). Paired with the Desco 50755 ESD Glove Test Fixture, operators can test while wearing ESD gloves or finger cots.

Standards

Suitable as test equipment for compliance verification to IEC 61340-5-1 and ANSI/ESD S20.20 (tested per ESD TR53). Wrist straps worn daily should be tested daily.
