SEW 4167MF Insulation & Multifunction Tester

Product Description

SEW 4167MF Insulation & Multifunction Tester

The SEW 4167 MF is a versatile testing instrument that combines insulation resistance, earth resistance, and voltage measurement capabilities into a single compact unit. It’s designed for electrical installations, maintenance, and troubleshooting.

Features:

•  High Quality Taut Band movement.
•  Capable of measuring earth resistance and earth voltage.
•  2mA measuring current permits the testing of earth resistance without tripping earth leakage current
• breakers in the circuit under test.
•  Test leads are supplied as standard accessories for simplified two-wire measuring system.
•  Two insulation test voltages(DC) : 250V and 500V.
•  Alternation voltage measurement.
•  Battery life indicator.
•  Fuse protected.
