Product Details

What Makes the EEC-31 Hipot Tester Different

Most entry-level electrical safety testers cover AC Withstand testing and nothing else. When compliance requirements change, or when a new product line introduces DC or insulation resistance testing requirements, you would need to purchase additional instruments and train operators on additional equipment. The EEC-31 eliminates that problem.
