An ESD Combo Tester is a testing tool which is highly reliable in measuring the efficiency of personal grounding equipment like ESD wrist straps and footwear. It is important in the control programme of electrostatic discharge programmes, as operators are grounded well before they enter into the ESD-protected zones. The tester quickly tests the resistance levels and provides pass or fail results with easy-to-see and/or audible results to ensure that fragile electronic parts are not destroyed. The ESD Combo Tester is made of durable materials; therefore, it is applicable in electronics manufacturing plants, cleanrooms, labs and assembly lines. It is user-friendly, has very little maintenance need and provides precise and consistent results. The small size can be easily installed at the entry points. The tester will improve the safety of the workplace, minimise product failures, and ensure that all grounding systems conform to the ESD control standards, which makes it a critical part of any ESD-safe environment.
