IET LABS 1888 Megohmmeter

IET 1888 Megohmmeter / High Resistance Meter – IET Labs

Advanced High Resistance Measurement for Laboratory and Production Use

The IET Labs 1888 Megohmmeter is a high-performance, microprocessor-based instrument designed to measure extremely high resistance with excellent precision. It replaces the IET 1865 Plus, offering upgraded features, enhanced usability, and broader measurement capabilities. Built for both benchtop and automated systems, the 1888 is ideal for research labs, metrology, quality assurance, and component manufacturing environments.

Its resistance range extends from 1 kΩ up to 1,000 TΩ, depending on the applied voltage, making it suitable for a wide array of testing scenarios. The intuitive graphical touchscreen simplifies operation by displaying voltage, current, resistance, and settings all on one screen—with selectable data formats such as graphs, charts, and tables for easy analysis.
