SEW Analogue Insulation tester
The SEW 1131IN is a robust analogue insulation and continuity tester. Designed firstly for everyday testing of electrical installations. Motors and electrical components. This is an excellent unit with three test ranges of 250V, 500V and also 1000V. The 1131 is compact and lightweight. Furthermore features include AC Voltmeter. Continuity and automatic discharge of capacitive and inductive circuits with charge stored in the circuit under test. The unit is especially good value for money.
High quality Taut Band movement.
Three insulation test voltages(DC) : 250V, 500V, 1000V.
Two ranges for continuity test : 2Ω & 20Ω.
Compact and also lightweight.
