SecuTest SIII+ Safety Tester

For Testing the Electrical Safety of Portable Electrical Equipment in Commercial and Medical Applications

Universal Electrical Safety Tester with Test Sequences per IEC 61010, 60335 and 60950
SecuTest SIII+ Safety Tester


The SecuTest SIII+ is a universal test instrument that is ideal for testing the electrical safety of portable electrical equipment in commercial and medical applications. In order to evaluate electrical safety, tests are performed for protective conductor connections, insulation resistance, and leakage current (differential current, equivalent leakage current, device leakage current, patient leakage current, and contact current). The SecuTest SIII+ provides test sequences per IEC 62353: Medical electrical equipment - Recurrent test and test after repair of medical electrical equipment, IEC 61010: Safety requirements for electrical equipment for measurement, control, and laboratory use, IEC 60335: Safety of electrical household appliances, IEC 60950: Safety of information technology equipment, and IEC 60601: Medical Electrical Equipment (optional).
