IET 1865Plus digital megohm meter I/R tester

The IET Labs 1865Plus megohm meter / IR tester, with digital display, is used for high accuracy measurements of insulation resistance on a wide variety of components, materials and electronic devices.

IET 1865Plus megohmmeter, IC tester
Resistance values greater than 100 teraohms can be measured with a basic accuracy of 0.5% at DC voltages up to 1000V.

A programmable limit makes the IET Labs megohm meter ideal for pass / fail testing in a production environment and is also adaptable for use in automated system applications with its included RS-232 Interface or optional IEEE-488 interface adapter.

Unit comes with optional CE marking which is a mandatory conformance mark for products being used in Europe
